Merge tag 'sound-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "We've received a lot of activities in this cycle, mostly about leaf driver codes rather than the core part, but with a good mixture of code cleanups and new driver additions. Below are some highlights: ASoC: - Support for automatically enumerating DAIs from standards conforming SoundWire SDCA devices; not much used as of this writing, rather for future implementations - Conversion of quite a few drivers to newer GPIO APIs - Continued cleanups and helper usages in allover places - Support for a wider range of Intel AVS platforms - Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32 Everest Semiconductor ES8375 and ES8389, Longsoon-1 AC'97 controllers, nVidia Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers HD-audio: - Lots of cleanups of TAS2781 codec drivers - A new HD-audio control bound via ACPI for Nvidia - Support for Tegra264, Intel WCL, usual new codec quirks USB-audio: - Fix a race at removal of MIDI device - Pioneer DJM-V10 support, Scarlett2 driver cleanups Misc: - Cleanups of deprecated PCI functions - Removal of unused / dead function codes" * tag 'sound-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (364 commits) firmware: cs_dsp: Fix OOB memory read access in KUnit test ASoC: codecs: add support for ES8375 ASoC: dt-bindings: Add Everest ES8375 audio CODEC ALSA: hda: acpi: Make driver's match data const static ALSA: hda: acpi: Use SYSTEM_SLEEP_PM_OPS() ALSA: atmel: Replace deprecated strcpy() with strscpy() ALSA: core: fix up bus match const issues.
