Merge tag 'sound-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "We've received a fairly wide range of changes at this time, including for ALSA and ASoC core, but all of them are rather small changes. Here are some highlights: ALSA / ASoC Core: - Fixes of inconsistent locking around control API helpers - A few new control API functions and cleanups - Workarounds for potential UAFs by delayed kobj releases - Unified PCM copy ops with iov_iter - Continued efforts for ASoC API cleanups ASoC: - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in some IIO changes - Create a library function for intlog10() and use it in the NAU8825 driver - Convert drivers to use the more modern maple tree register cache - Lots of work on the SOF framework, AMD and Intel drivers, including a lot of cleanup and new device support - Standardization of the presentation of jacks from drivers - Provision of some generic sound card DT properties - Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821, AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel platforms including AVS machines with ES8336 and RT5663, Mediatek MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110 Others: - New test coverage including ASoC and topology tests in KUnit; this also involves enabling UML builds of ALSA since that's the default KUnit test environment which pulls in the addition of some stubs to the driver - More enhancement of pcmtest driver - A few fixes / enhancements of MIDI 2.0 UMP core - Using PCI definitions in allover HD-audio code - Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs - CS35L41 HD-audio sub-codec improvements - Continued emu10k1 improvements" * tag 'sound-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (693 commits) ALSA: pcm: Fix missing fixup call in compat hw_refine ioctl ASoC: dwc: i2s: Fix unused functions ALSA: usb-audio: Don't try to submit URBs after disconnection ALSA: emu10k1: add separate documentation for E-MU cards ALSA: emu10k1: more documentation updates ALSA: emu10k1: de-duplicate audigy-mixer.rst vs. sb-live-mixer.rst ALSA: ump: Fix -Wformat-truncation warnings ALSA: hda: Add missing dependency on CONFIG_EFI for Cirrus/TI sub-codecs ALSA: doc: Fix missing backquote in midi-2.0.rst ALSA: hda/realtek: Add quirk for mute LEDs on HP ENVY x360 15-eu0xxx ALSA: hda/tas2781: Switch back to use struct i2c_driver's .probe() ASoC: soc-core.c: Do not error if a DAI link component is not found ASoC: codecs: Fix error code in aw88261_i2c_probe() ASoC: audio-graph-card.c: move audio_graph_parse_of() ASoC: cs42l43: Use new-style PM runtime macros ALSA: documentation: Add description for USB MIDI 2.0 gadget driver ALSA: ump: Don't create unused substreams for static blocks ALSA: ump: Fill group names for legacy rawmidi substreams ALSA: usb-audio: Attach legacy rawmidi after probing all UMP EPs ALSA: ac97: Fix possible error value of *rac97 ...
