simple-mux immediately activates the new output, even when it is powered

So far the mux changes it state immediately, even when not in use. Allow
overriding this behaviour by specifying an optional idle-state. This
state is used whenever the mux is powered down, only switching to the
selected state on power up. If unspecified it defaults to as-is,
maintaining the previous behaviour.

Fixed PCM device numbering is required for defining common alsa ucm
changes for generic soundwire machine driver for legacy(No DSP) stack.
Ex: For Headphone playback use case, use PCM device number as 0.
For Headset mic Capture use case, PCM device number as 1.
Set the 'use_dai_pcm_id' flag true in soundwire dma driver for acp 6.3
platform. This will fix the pcm device numbering based on dai_link->id.

The current 6fire code tries to release the resources right after the
call of usb6fire_chip_abort(). But at this moment, the card object
might be still in use (as we're calling snd_card_free_when_closed()).
For avoid potential UAFs, move the release of resources to the card's
private_free instead of the manual call of usb6fire_chip_destroy() at
the USB disconnect callback.

The USB disconnect callback is supposed to be short and not too-long
waiting. OTOH, the current code uses snd_card_free() at
disconnection, but this waits for the close of all used fds, hence it
can take long. It eventually blocks the upper layer USB ioctls, which
may trigger a soft lockup.
An easy workaround is to replace snd_card_free() with
snd_card_free_when_closed(). This variant returns immediately while
the release of resources is done asynchronously by the card device
release at the last close.
This patch also splits the code to the disconnect and the free phases;
the former is called immediately at the USB disconnect callback while
the latter is called from the card destructor.

Simple Card Utils has simple_util_dai which is paired to snd_soc_dai,
and assmus that CPU/Codec DAI and its paired simple_util_dai are same
order for CPU/Codec
simple_util_dai[0] <--> snd_soc_dai[0]
simple_util_dai[1] <--> snd_soc_dai[1]
...
So, it is using same index in for_each loop.
(X) gets simple_util_dai
(Y) gets snd_soc_dai
(Y) for_each_rtd_cpu_dais(.., i, ..) {
(X)(A) udai = simple_props_to_dai_cpu(.., i);
}
(X) for_each_prop_dai_cpu(.., i, ...) {
(Y) dai = snd_soc_rtd_to_cpu(.., i);
...
}
But current Simple Card Utils didn't have simple_util_dai for
dummy DAI. So above (A) will get NULL pointer in such case.
This patch cares simple_util_dai for dummy DAI.

Fix an issue detected by the Smatch tool:
sound/soc/sof/ipc4-pcm.c: sof_ipc4_pcm_dai_link_fixup_rate()
error: uninitialized symbol 'be_rate'.
The warning highlights a case where `be_rate` could remain uninitialized
if `num_input_formats` is zero, which would cause undefined behavior
when setting `rate->min` and `rate->max` based on `be_rate`.
To address this issue, a `WARN_ON_ONCE(!num_input_formats)` check was
added to ensure `num_input_formats` is greater than zero. If this
condition fails, the function returns `-EINVAL`, preventing the use of
an uninitialized `be_rate`.
This change improves the robustness of the function by catching an
invalid state early and providing better feedback during development.

Add STM32MP25 support for STM32 I2S.
On STM32MP25 the I2S driver does not manage I2S kernel clock rate
by choosing its parent clock, depending on audio stream rate.
The driver requests a rate change on I2S kernel clock instead.
It tries to set the higher possible rate, which is a multiple of
the audio stream rate and which gives an accuracy of at least 1000 ppm.

Add STM32MP25 support for STM32 SAI.
On STM32MP25 the SAI driver does not manage SAI kernel clock rate
by chosing its parent clock, dependending on audio stream rate.
The driver requests a rate change on SAI kernel clock instead.
This rate change is performed with the following guidelines:
- Chose highest rate multiple of the audio stream
(Try to get clock accuracy within 1000 ppm)
- Ensure clock rate compatibility between SAI sub-blocks A&B
and between instances sharing the same flexgen.
Use clk_rate_exclusive API to fulfill this requirement.
The STM32 SAI peripheral does not support the DMA burst mode
on STM32MP25. Add a field in compatible structure to manage DMA
burst support capability.

Reproducer uses faultinject facility to fail ocfs2_xa_remove() ->
ocfs2_xa_value_truncate() with -ENOMEM.
In this case the comment mentions that we can return 0 if
ocfs2_xa_cleanup_value_truncate() is going to wipe the entry
anyway. But the following 'rc' check is wrong and execution flow do
'ocfs2_xa_remove_entry(loc);' twice:
* 1st: in ocfs2_xa_cleanup_value_truncate();
* 2nd: returning back to ocfs2_xa_remove() instead of going to 'out'.
Fix this by skipping the 2nd removal of the same entry and making
syzkaller repro happy.

Prior to commit d64696905554 ("Reimplement RLIMIT_SIGPENDING on top of
ucounts") UCOUNT_RLIMIT_SIGPENDING rlimit was not enforced for a class of
signals. However now it's enforced unconditionally, even if
override_rlimit is set. This behavior change caused production issues.
For example, if the limit is reached and a process receives a SIGSEGV
signal, sigqueue_alloc fails to allocate the necessary resources for the
signal delivery, preventing the signal from being delivered with siginfo.
This prevents the process from correctly identifying the fault address and
handling the error. From the user-space perspective, applications are
unaware that the limit has been reached and that the siginfo is
effectively 'corrupted'. This can lead to unpredictable behavior and
crashes, as we observed with java applications.
Fix this by passing override_rlimit into inc_rlimit_get_ucounts() and skip
the comparison to max there if override_rlimit is set. This effectively
restores the old behavior.
