ASoC: tlv320aic32x4: Make aic32x4_remove() return void

Up to now aic32x4_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.

block, bfq: reset last_bfqq_created on group change

Since commit 430a67f9d616 ("block, bfq: merge bursts of newly-created
queues"), BFQ maintains a per-group pointer to the last bfq_queue
created. If such a queue, say bfqq, happens to move to a different
group, then bfqq is no more a valid last bfq_queue created for its
previous group. That pointer must then be cleared. Not resetting such
a pointer may also cause UAF, if bfqq happens to also be freed after
being moved to a different group. This commit performs this missing
reset. As such it fixes commit 430a67f9d616 ("block, bfq: merge bursts
of newly-created queues").

Such a missing reset is most likely the cause of the crash reported in [1].
With some analysis, we found that this crash was due to the
above UAF. And such UAF did go away with this commit applied [1].

Anyway, before this commit, that crash happened to be triggered in
conjunction with commit 2d52c58b9c9b ("block, bfq: honor already-setup
queue merges"). The latter was then reverted by commit ebc69e897e17
("Revert "block, bfq: honor already-setup queue merges""). Yet commit
2d52c58b9c9b ("block, bfq: honor already-setup queue merges") contains
no error related with the above UAF, and can then be restored.

brd: reduce the brd_devices_mutex scope

As with commit 8b52d8be86d72308 ("loop: reorder loop_exit"),
unregister_blkdev() needs to be called first in order to avoid calling
brd_alloc() from brd_probe() after brd_del_one() from brd_exit(). Then,
we can avoid holding global mutex during add_disk()/del_gendisk() as with
commit 1c500ad706383f1a ("loop: reduce the loop_ctl_mutex scope").

ASoC: rockchip: i2s-tdm: Strip out direct CRU use

In cases where both rx and tx lrck are synced to the same source,
the resets for rx and tx need to be triggered simultaneously,
according to the downstream driver.

As there is no reset API to atomically bulk (de)assert two resets
at once, what the driver did was implement half a reset controller
specific to Rockchip, which tried to write the registers for the
resets within one write ideally or several writes within an irqsave
section.

This of course violates abstractions quite badly. The driver should
not write to the CRU's registers directly.

In practice, for the cases I tested the driver with, which is audio
playback, replacing the synchronised asserts with just individual
ones does not seem to make any difference.

If it turns out that this breaks something in the future, it should
be fixed through the specification and implementation of an atomic
bulk reset API, not with a CRU hack.

x86/fpu: Mask out the invalid MXCSR bits properly

This is a fix for the fix (yeah, /facepalm).

The correct mask to use is not the negation of the MXCSR_MASK but the
actual mask which contains the supported bits in the MXCSR register.

Input: touchscreen - avoid bitwise vs logical OR warning

A new warning in clang points out a few places in this driver where a
bitwise OR is being used with boolean types:

drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]
data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This use of a bitwise OR is intentional, as bitwise operations do not
short circuit, which allows all the calls to touchscreen_get_prop_u32()
to happen so that the last parameter is initialized while coalescing the
results of the calls to make a decision after they are all evaluated.

To make this clearer to the compiler, use the '|=' operator to assign
the result of each touchscreen_get_prop_u32() call to data_present,
which keeps the meaning of the code the same but makes it obvious that
every one of these calls is expected to happen.

Input: snvs_pwrkey - add clk handling

On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
associated clock. Accessing the registers requires that this clock is
enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
having the clock enabled results in a complete hang of the machine.
(This usually only happens if snvs_pwrkey is built as a module and the
rtc-snvs driver isn't already bound because at bootup the required clk
is on and only gets disabled when the clk framework disables unused clks
late during boot.)

This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add
snvs clock to pwrkey").

nds32/ftrace: Fix Error: invalid operands (*UND* and *UND* sections) for `^'

I received a build failure for a new patch I'm working on the nds32
architecture, and when I went to test it, I couldn't get to my build error,
because it failed to build with a bunch of:

  Error: invalid operands (*UND* and *UND* sections) for `^'

issues with various files. Those files were temporary asm files that looked
like:  kernel/.tmp_mc_fork.s

I decided to look deeper, and found that the "mc" portion of that name
stood for "mcount", and was created by the recordmcount.pl script. One that
I wrote over a decade ago. Once I knew the source of the problem, I was
able to investigate it further.

The way the recordmcount.pl script works (BTW, there's a C version that
simply modifies the ELF object) is by doing an "objdump" on the object
file. Looks for all the calls to "mcount", and creates an offset of those
locations from some global variable it can use (usually a global function
name, found with <.*>:). Creates a asm file that is a table of references
to these locations, using the found variable/function. Compiles it and
links it back into the original object file. This asm file is called
".tmp_mc_<object_base_name>.s".

The problem here is that the objdump produced by the nds32 object file,
contains things that look like:

0000159a <.L3^B1>:
    159a:       c6 00           beqz38 $r6, 159a <.L3^B1>
                        159a: R_NDS32_9_PCREL_RELA      .text+0x159e
    159c:       84 d2           movi55 $r6, #-14
    159e:       80 06           mov55 $r0, $r6
    15a0:       ec 3c           addi10.sp #0x3c

Where ".L3^B1 is somehow selected as the "global" variable to index off of.

Then the assembly file that holds the mcount locations looks like this:

        .section __mcount_loc,"a",@progbits
        .align 2
        .long .L3^B1 + -5522
        .long .L3^B1 + -5384
        .long .L3^B1 + -5270
        .long .L3^B1 + -5098
        .long .L3^B1 + -4970
        .long .L3^B1 + -4758
        .long .L3^B1 + -4122
        [...]

And when it is compiled back to an object to link to the original object,
the compile fails on the "^" symbol.

Simple solution for now, is to have the perl script ignore using function
symbols that have an "^" in the name.

Merge series "ASoC: Add Audio Graph Card2 support" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

We already have Audio-Graph-Card which is Of-Graph base general sound
card driver. Basically it supports basic CPU-Codec connection, and is
also supporting DPCM connection. Because it was forcibly expanded to
DPCM, DT parsing is very limited and very difficult to add new features
on it, for example Multi-CPU/Codec support, Codec2Codec support, etc.

This patch adds more flexible new Audio-Graph-Card2 driver for it.
Audio-Graph-Card and Audio-Graph-Card2 are similar, but don't have
full compatibility.
The reason why I need Audio-Graph-Card2 instead of updating Audio-Graph-Card
is that it is very difficult to keep compatibility.

Audio-Graph-Card2 supports Normal/DPCM/Codec2Codec Connection wich
Single/Multi DAIs. And it is possible to Customizing.

This patch-set adds Audio-Graph-Card2 driver and its custom driver
sample, and DT settings sample which can be used for testing.

To enable testing/debuging, this patch-set also adds Test-Component
driver. We already have Dummy Component and/or Dummy DAI on soc-utils,
but 1) we can't use it from DT, 2) it do nothing.
Added new Test-Component can be used from DT, and it can indicate called
function name. We can use it to trace callback order, understanding
ALSA SoC behavior, etc, etc...
Sample DT settings of Audio Graph Card2 is using Test-Component as CPU/Codec DAI.

You can easily try to use/test it if you added below line to your DT file.
Your .config needs to have below CONFIGs to use/test it.
It will probe sample Sound Card which has Normal/DPCM/Multi/Codec2Codec
connections.

#include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi"

CONFIG_SND_AUDIO_GRAPH_CARD2
CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
CONFIG_SND_TEST_COMPONENT

Because Audio Graph Card2 is still under experimental stage, it will
indicate such warning when probing, and the DT might be updated/exchanged.

It can use Codec2Codec, but it will start automatically when probed,
and can't stop it so far. It should be updated.

ASoC: audio-graph-card2-custom-sample.dtsi: add Sample DT for Normal (Single)

Audio Graph Card2 settings is a little bit difficult for beginner,
and Customizing it also difficult/confusable too.
So, this patch adds sample for it.

You can easily use it by adding below line on your DT file,
and select CONFIGs to your .config.

#include "../../../../../sound/soc/generic/audio-graph-card2-custom-sample.dtsi"

CONFIG_SND_AUDIO_GRAPH_CARD2
CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
CONFIG_SND_TEST_COMPONENT

This patch uses audio-graph-card2 base custom sample driver.
You can directly use audio-graph-card2 instead of custom sample driver
by modifing compatible.

- compatible = "audio-graph-card2-custom-sample";
+ compatible = "audio-graph-card2";

Sample custom driver will indicate customized print.

It is using Test-Component driver for CPU/Codec.
It can indicate more detail print of each behavior if user want to.
In such case, you need to update compatible to "xxx-nv" or "xxx-vv".

- compatible = "test-cpu";
+ compatible = "test-cpu-verbose";

ASoC: audio-graph-card2: add Codec2Codec support

This patch adds Codec2Codec support to audio-graph-card2.
It can use Codec2Codec but very simple case only for now.
It doesn't have "SWITCH" control yet, thus it start automatically
when it was probed, and can't stop, so far.
Thus it needs to be updated around widgets/routing handling,
and you need to understand that it is under experimental.

Codec has SND_SOC_DAPM_INPUT() (= IN) / SND_SOC_DAPM_OUTPUT(= OUT)
widgets in below case.

It is assuming 2channel, S32_LE format for now.
It needs to be updated, too.

It needs "codec2codec" node (= B), needs to have routing (= A),
need to indicate CPU side at links (= X).
ports@0 is for CPU side (= X), port@1 is Codec side (= Y).

ASoC: add Audio Graph Card2 driver

We already have audio-graph-card which is Of-graph base of general
sound card driver.

It is supporting DPCM connection, but was forcibly expanded.
Thus, it is very difficult to add new features on it, for example
Multi CPU/Codec support, Codec2Codec support, etc.

This patch adds more flexible new Audio Graph Card2 driver for it.
audio-graph-card and audio-graph-card2 are similar, but don't have
full compatibility.

Audio Graph Card2 supports very generic connection, but some users
want to have its own settings, for example PLL settings, etc.
For such case, it has customizing support.
In users own driver, it can use Audio Graph Card2 parsing by using
audio_graph2_parse_of(), and doing its own customizing.

Because Audio Graph Card2 is still under experimental stage,
it will indicate such warning when probing, and the DT syntax
might be changed.

We already have dummy-codec, dummy-platform.
But its issues are

2) we can't select it via DeviceTree
3) It do nothing

User can select CPU   Component by using "test-cpu"   compatible,
and  can select Codec Component by using "test-codec" compatible.

It doesn't support Platform so far, but is easy to add.

We can verbose print to know its progress if user selected
xxx-verbose compatible driver.

KVM: PPC: Book3S HV: Make idle_kvm_start_guest() return 0 if it went to guest

We call idle_kvm_start_guest() from power7_offline() if the thread has
been requested to enter KVM. We pass it the SRR1 value that was returned
from power7_idle_insn() which tells us what sort of wakeup we're
processing.

Depending on the SRR1 value we pass in, the KVM code might enter the
guest, or it might return to us to do some host action if the wakeup
requires it.

If idle_kvm_start_guest() is able to handle the wakeup, and enter the
guest it is supposed to indicate that by returning a zero SRR1 value to
us.

That was the behaviour prior to commit 10d91611f426 ("powerpc/64s:
Reimplement book3s idle code in C"), however in that commit the
handling of SRR1 was reworked, and the zeroing behaviour was lost.

Returning from idle_kvm_start_guest() without zeroing the SRR1 value can
confuse the host offline code, causing the guest to crash and other
weirdness.

KVM: PPC: Book3S HV: Fix stack handling in idle_kvm_start_guest()

In commit 10d91611f426 ("powerpc/64s: Reimplement book3s idle code in
C") kvm_start_guest() became idle_kvm_start_guest(). The old code
allocated a stack frame on the emergency stack, but didn't use the
frame to store anything, and also didn't store anything in its caller's
frame.

idle_kvm_start_guest() on the other hand is written more like a normal C
function, it creates a frame on entry, and also stores CR/LR into its
callers frame (per the ABI). The problem is that there is no caller
frame on the emergency stack.

The emergency stack for a given CPU is allocated with:

paca_ptrs[i]->emergency_sp = alloc_stack(limit, i) + THREAD_SIZE;

So emergency_sp actually points to the first address above the emergency
stack allocation for a given CPU, we must not store above it without
first decrementing it to create a frame. This is different to the
regular kernel stack, paca->kstack, which is initialised to point at an
initial frame that is ready to use.

idle_kvm_start_guest() stores the backchain, CR and LR all of which
write outside the allocation for the emergency stack. It then creates a
stack frame and saves the non-volatile registers. Unfortunately the
frame it creates is not large enough to fit the non-volatiles, and so
the saving of the non-volatile registers also writes outside the
emergency stack allocation.

The end result is that we corrupt whatever is at 0-24 bytes, and 112-248
bytes above the emergency stack allocation.

In practice this has gone unnoticed because the memory immediately above
the emergency stack happens to be used for other stack allocations,
either another CPUs mc_emergency_sp or an IRQ stack. See the order of
calls to irqstack_early_init() and emergency_stack_init().

The low addresses of another stack are the top of that stack, and so are
only used if that stack is under extreme pressue, which essentially
never happens in practice - and if it did there's a high likelyhood we'd
crash due to that stack overflowing.

Still, we shouldn't be corrupting someone else's stack, and it is purely
luck that we aren't corrupting something else.

To fix it we save CR/LR into the caller's frame using the existing r1 on
entry, we then create a SWITCH_FRAME_SIZE frame (which has space for
pt_regs) on the emergency stack with the backchain pointing to the

eeprom: 93xx46: fix MODULE_DEVICE_TABLE

The newly added SPI device ID table does not work because the
entry is incorrectly copied from the OF device table.

During build testing, this shows as a compile failure when building
it as a loadable module:

drm/nouveau/fifo: Reinstate the correct engine bit programming

Commit 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") replaced
fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of
fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned
from the later g84_fifo_engine_id() are incremented by 1 compared to
the previous g84_fifo_chan_engine() return values.

This is fine either way for most of the code, except this one line
where an engine bit programmed into the hardware is derived from the
return value. Decrement the return value accordingly, otherwise the
wrong engine bit is programmed into the hardware and that leads to
the following failure:

drm/hyperv: Fix double mouse pointers

Hyper-V supports a hardware cursor feature. It is not used by Linux VM,
but the Hyper-V host still draws a point as an extra mouse pointer,
which is unwanted, especially when Xorg is running.

The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer.
When the hyperv_drm driver was developed, the function synthvid_send_ptr()
was not copied from the hyperv_fb driver. Fix the issue by adding the
function into hyperv_drm.

drm/edid: In connector_bad_edid() cap num_of_ext by num_blocks read

In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid
corruption test") the function connector_bad_edid() started assuming
that the memory for the EDID passed to it was big enough to hold
`edid[0x7e] + 1` blocks of data (1 extra for the base block). It
completely ignored the fact that the function was passed `num_blocks`
which indicated how much memory had been allocated for the EDID.

Let's fix this by adding a bounds check.

This is important for handling the case where there's an error in the
first block of the EDID. In that case we will call
connector_bad_edid() without having re-allocated memory based on
`edid[0x7e]`.

libperf tests: Fix test_stat_cpu

The `cpu` argument of perf_evsel__read() must specify the cpu index.

perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index)
and is thus not appropriate for use with perf_evsel__read().

So, if there is an offline CPU, the cpu number specified in the argument
may point out of range because the cpu number and the cpu index are
different.

Fix test_stat_cpu().

decompressed records in raw trace dump (-D option of perf-report):
