Pull sound updates from Takashi Iwai:
"It's been relatively calm in this cycle from the feature POV, but
there were lots of cleanup works in the wide-range of code for
converting with the auto-cleanup macros like guard().

The mostly user-visible changes are the support of a couple of new
compress-offload API extensions, and the support of new ASoC codec /
platform drivers as well as USB-audio quirks.

Here we go with some highlights:

Core:
- Compress-offload API extension for 64bit timestamp support
- Compress-offload API extension for OPUS codec support
- Workaround for PCM locking issue with PREEMPT_RT and softirq
- KCSAN warning fix for ALSA sequencer core

ASoC:
- Continued cleanup works for ASoC core APIs
- Lots of cleanups and conversions of DT bindings
- Substantial maintainance work on the Intel AVS drivers
- Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
FourSemi FS2104/5S, Texas Instruments PCM1754 and TAS2783A
- Remove support for TI WL1273 for old Nokia systems

USB-audio:
- Support for Tascam US-144mkII, Presonus S1824c support
- More flexible quirk option handling
- Fix for USB MIDI timer bug triggered by fuzzer

Others:
- A large series of cleanups with guard() & co macros over (non-ASoC)
sound drivers (PCI, ISA, HD-audio, USB-audio, drivers, etc)
- TAS5825 HD-audio side-codec support"

ASoC: Updates for v6.18

A relatively quiet release for ASoC, we've had a lot of maintainance
work going on and several new drivers but really the most remarkable
thing is that we removed a driver, the WL1273 driver used in some old
Nokia systems that have had the underlying system support removed from
the kernel.

- Morimoto-san continues his work on cleanups of the core APIs and
enforcement of abstraction layers.
- Lots of cleanups and conversions of DT bindings.
- Substantial maintainance work on the Intel AVS drivers.
- Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
FourSemi FS2104/5S, Texas Instruments PCM1754.
- Remove support for TI WL1273.

ASoC: Use kcalloc() instead of kzalloc()

ASoC: Use kcalloc() instead of kzalloc()

Merge series from Qianfeng Rong <rongqianfeng@vivo.com>:

Replace devm_kzalloc() with devm_kcalloc() in sound/soc. As noted in the
kernel documentation [1], open-coded multiplication in allocator arguments
is discouraged because it can lead to integer overflow.

Using devm_kcalloc() provides built-in overflow protection, making the
memory allocation safer when calculating the allocation size compared
to explicit multiplication.

ASoC: codecs: Add library for FourSemi audio amplifiers

This patch adds firmware loading and parsing support for FourSemi audio
amplifiers. The library handles firmware file (*.bin) generated by the
FourSemi tuning tool, which contains:
- Register initialization settings
- DSP effect parameters
- Multi-scene sound effect switching configurations(optional)

The firmware is required for proper initialization and configuration
of FourSemi amplifier devices.
