bclk = sample_rate * N * W
As a convenience to simplify calling code, if the slot count or
slot width are 0 a value will be obtained from the params. This
allows calling code to use this one function to handle cases of
TDM where only one parameter is fixed, or I2S where the slot width
is fixed (for example to set a 32-bit slot for 24-bit samples).
Also as a convenience the slot count can optionally be rounded up

ASoC: soc-dapm: fix two incorrect uses of list iterator
These two bug are here:
list_for_each_entry_safe_continue(w, n, list,
power_list);
list_for_each_entry_safe_continue(w, n, list,
power_list);
After the list_for_each_entry_safe_continue() exits, the list iterator
will always be a bogus pointer which point to an invalid struct objdect
containing HEAD member. The funciton poniter 'w->event' will be a
invalid value which can lead to a control-flow hijack if the 'w' can be
controlled.
The original intention was to continue the outer list_for_each_entry_safe()
loop with the same entry if w->event is NULL, but misunderstanding the
meaning of list_for_each_entry_safe_continue().
So just add a 'continue;' to fix the bug.

using PLLB and programmed to 12MHz. As originally written for use with a
board file the audio driver was responsible for configuring the entire tree
but in the conversion to the common clock framework the registration of
the named pck0 and pllb clocks was removed so the driver has failed to

Since the WM8731 driver has had support for managing a MCLK provided via
the common clock framework for some time we can simply drop all the clock
management code from the machine driver other than configuration of the
sysclk rate, the CODEC driver still respects that configuration from the

Asynchronous Sample Rate Converter (ASRC) converts the sampling frequency
of the input signal from one frequency to another. It can handle over a
wide range of sample rate ratios (freq_in/freq_out) from 1:24 to 24:1.
ASRC has two modes of operation. One where ratio can be programmed in SW
and the other where it gets the information from ratio estimator module.
The latter mode above can help address the cases where the sample rate is
not known at the stream set up time or is potentially time varying.
In addition, the ratio between input and output sample rate can be any
arbitrary number and the input and output clocks could be derived from
asynchronous clocks.
This patch registers ASRC driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes ASRC interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build

Merge tag 'trace-v5.18-2' of git://git./linux/kernel/git/rostedt/linux-trace
Pull more tracing updates from Steven Rostedt:
- Rename the staging files to give them some meaning. Just
stage1,stag2,etc, does not show what they are for
- Check for NULL from allocation in bootconfig
- Hold event mutex for dyn_event call in user events
- Mark user events to broken (to work on the API)
- Remove eBPF updates from user events
- Remove user events from uapi header to keep it from being installed.
- Move ftrace_graph_is_dead() into inline as it is called from hot
paths and also convert it into a static branch.

"A single revert to fix a boot regression seen when clk_put() started
dropping rate range requests. It's best to keep various systems
booting so we'll kick this out and try again next time"

Pull x86 fixes from Thomas Gleixner:
"A set of x86 fixes and updates:
- Make the prctl() for enabling dynamic XSTATE components correct so
it adds the newly requested feature to the permission bitmap
instead of overwriting it. Add a selftest which validates that.
- Unroll string MMIO for encrypted SEV guests as the hypervisor
cannot emulate it.
- Handle supervisor states correctly in the FPU/XSTATE code so it
takes the feature set of the fpstate buffer into account. The
feature sets can differ between host and guest buffers. Guest
buffers do not contain supervisor states. So far this was not an
issue, but with enabling PASID it needs to be handled in the buffer
offset calculation and in the permission bitmaps.
- Avoid a gazillion of repeated CPUID invocations in by caching the
values early in the FPU/XSTATE code.
- Enable CONFIG_WERROR in x86 defconfig.
- Make the X86 defconfigs more useful by adapting them to Y2022
reality"
