ASoC: Updates for v6.13
This release was mainly about new drivers, there's a very large batch of
new drivers and devices including quite a few from newer vendors which
is great to see. Other than the new drivers and the usual routine fixes
and enhancements the bulk of the work has been Morimoto-san's continuing
work on simplifiying APIs, plus a few other bits:
- More API simplifications from Morimoto-san.
- Renaming of the sh directory to Renesas to reflect the focus on other
architectures.
- Factoring out of some of the common code for Realtek devices.
- Support for Allwinner H616, AMD ACP 6.3 systems, AWInic AW88081,
Cirrus Logic CS32L84, Everest ES8328, Iron Devices SMA1307, Longsoon

The reason is that SND_SOC_ACPI_INTEL_MATCH is needed to be compilable

signal: restore the override_rlimit logic
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.
