ASoC: rt5645: Avoid upgrading static warnings to errors

One of the fixes reverted as part of the UMN fallout was actually fine,
however rather than undoing the revert the process that handled all this
stuff resulted in a patch which attempted to add extra error checks
instead.  Unfortunately this new change wasn't really based on a good
understanding of the subsystem APIs and bypassed the usual patch flow
without ensuring it was reviewed by people with subsystem knowledge and
was merged as a fix rather than during the merge window.

The effect of the new fix is to upgrade what were previously warnings on
static data in the code to hard errors on that data.  If this actually
happens then it would break existing systems, if it doesn't happen then
the change has no effect so this was not a safe change to apply as a fix
to the release candidates.  Since the new code has not been tested and
doesn't in practice improve error handling revert it instead, and also
drop the original revert since the original fix was fine.  This takes
the driver back to what it was in -rc1.

ALSA: hda: Release controller display power during shutdown/reboot

Make sure the HDA driver's display power reference is released during
shutdown/reboot.

During the shutdown/reboot sequence the pci device core calls the
pm_runtime_resume handler for all devices before calling the driver's
shutdown callback and so the HDA driver's runtime resume callback will
acquire a display power reference (on HSW/BDW). This triggers a power
reference held WARN on HSW/BDW in the i915 driver's subsequent shutdown
handler, which expects all display power references to be released by
that time.

Since the HDA controller is stopped in the shutdown handler in any case,
let's follow here the same sequence as the one during runtime suspend.
This will also reset the HDA link and drop the display power reference,
getting rid of the above WARN.

Tested on HSW.

ALSA: usb-audio: scarlett2: Fix wrong resume call

The current way of the scarlett2 mixer code managing the
usb_mixer_elem_info object is wrong in two ways: it passes its
internal index to the head.id field, and the val_type field is
uninitialized.  This ended up with the wrong execution at the resume
because a bogus unit id is passed wrongly.  Also, in the later code
extensions, we'll have more mixer elements, and passing the index will
overflow the unit id size (of 256).

This patch corrects those issues.  It introduces a new value type,
USB_MIXER_BESPOKEN, which indicates a non-standard mixer element, and
use this type for all scarlett2 mixer elements, as well as

ASoC: rt711-sdca-sdw: fix race condition on system suspend

In the initial driver we cancelled deferred work, but there is still a
window of time where a new interrupt could result in new deferred work
executed after the link is disabled, leading to an IO error. While we
did not see this IO error on RT711-sdca-based platforms, the code pattern
is similar to the RT700 case where the IO error was noted, so the fix
is added for consistency.

This patch uses an 'disable_irq_lock' mutex to prevent new interrupts
from happening after the start of the system suspend. The choice of a
mutex v. a spinlock is mainly due to the time required to clear
interrupts, which requires a command to be transmitted by the
SoundWire host IP and acknowledged with an interrupt. The
'interrupt_callback' routine is also not meant to be called from an
interrupt context.

An additional 'disable_irq' flag prevents race conditions where the
status changes before the interrupts are disabled, but the workqueue
handling status changes is scheduled after the completion of the
system suspend. On resume the interrupts are re-enabled already by the
io_init routine so we only clear the flag.

The code is slightly different from the other codecs since the
interrupt callback deals with the SDCA interrupts, leading to a much
larger section that's protected by the mutex. The SoundWire interrupt
scheme requires a read after clearing a status, it's not clear from
the specifications what would happen if SDCA interrupts are disabled
in the middle of the sequence, so the entire interrupt status
read/write is kept as is, even if in the end we discard the
information.

ALSA: hda/realtek: Fix bass speaker DAC mapping for Asus UM431D

Asus Zenbook 14 UM431D has two speaker pins and a headphone pin, and
the auto-parser ends up assigning the bass to the third DAC 0x06.
Although the tone comes out, it's inconvenient because this DAC has no
volume control unlike two other DACs.

For obtaining the volume control for the bass speaker, this patch
enforces the mapping to let both front and bass speaker pins sharing
the same DAC.  It's not ideal but a little bit of improvement.

Since we've already applied the same workaround for another ASUS
machine, we just need to hook the chain to the existing quirk.

ALSA: bebob: add support for ToneWeal FW66

A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.

I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.

I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.

  perf: util/evsel.c:1596: get_group_fd: Assertion `!(!leader->core.fd)' failed.
  Aborted (core dumped)

The issue shows itself as a use-after-free in evlist__check_cpu_maps(),
whereby the leader of an event selector (evsel) has been deleted (yet we
still attempt to verify for an evsel).

Fundamentally the problem comes from metricgroup__setup_events() ->
find_evsel_group(), and has developed from the previous fix attempt in
commit 9c880c24cb0d ("perf metricgroup: Fix for metrics containing
duration_time").

The problem now is that the logic in checking if an evsel is in the same
group is subtly broken for the "cycles" event. For the "cycles" event,
the pmu_name is NULL; however the logic in find_evsel_group() may set an
event matched against "cycles" as used, when it should not be.

This leads to a condition where an evsel is set, yet its leader is not.

Fix the check for evsel pmu_name by not matching evsels when either has a
NULL pmu_name.

There is still a pre-existing metric issue whereby the ordering of the
metrics may break the 'stat' function, as discussed at:

After some investigation, I think I found the root cause: commit
2bfc6cd81bd ("move kernel mapping outside of linear mapping") moves
BPF JIT region after the kernel:

| #define BPF_JIT_REGION_START PFN_ALIGN((unsigned long)&_end)

The &_end is unlikely aligned with PMD size, so the front bpf jit
region sits with part of kernel .data section in one PMD size mapping.
But kernel is mapped in PMD SIZE, when bpf_jit_binary_lock_ro() is
called to make the first bpf jit prog ROX, we will make part of kernel
.data section RO too, so when we write to, for example memset the
.data section, MMU will trigger a store page fault.

To fix the issue, we need to ensure the BPF JIT region is PMD size
aligned. This patch acchieve this goal by restoring the BPF JIT region
to original position, I.E the 128MB before kernel .text section. The
modification to kasan_init.c is inspired by Alexandre.

riscv: kasan: Fix MODULES_VADDR evaluation due to local variables' name

commit 2bfc6cd81bd1 ("riscv: Move kernel mapping outside of linear
mapping") makes use of MODULES_VADDR to populate kernel, BPF, modules
mapping. Currently, MODULES_VADDR is defined as below for RV64:

| #define MODULES_VADDR   (PFN_ALIGN((unsigned long)&_end) - SZ_2G)

But kasan_init() has two local variables which are also named as _start,
_end, so MODULES_VADDR is evaluated with the local variable _end
rather than the global "_end" as we expected. Fix this issue by
renaming the two local variables.
