Merge tag 'sound-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
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" * tag 'sound-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (454 commits) ALSA: usb-audio: don't hardcode gain for output channel of Presonus Studio ALSA: usb-audio: add the initial mix for Presonus Studio 1824c ALSA: doc: improved docs about quirk_flags in snd-usb-audio ALSA: usb-audio: make param quirk_flags change-able in runtime ALSA: usb-audio: improve module param quirk_flags ALSA: usb-audio: add two-way convert between name and bit for QUIRK_FLAG_* ALSA: usb-audio: fix race condition to UAF in snd_usbmidi_free ALSA: usb-audio: add mono main switch to Presonus S1824c ALSA: compress: document 'chan_map' member in snd_dec_opus ASoC: cs35l56: Add support for CS35L56 B2 silicon ASoC: cs35l56: Set fw_regs table after getting REVID ALSA: hda/realtek: Add quirk for HP Spectre 14t-ea100 ASoc: tas2783A: Fix an error code in probe() ASoC: tlv320aic3x: Fix class-D initialization for tlv320aic3007 ASoC: qcom: sc8280xp: use sa8775p/ subdir for QCS9100 / QCS9075 ASoC: stm32: sai: manage context in set_sysclk callback ASoC: renesas: msiof: ignore 1st FSERR ASoC: renesas: msiof: Add note for The possibility of R/L opposite Capture ASoC: renesas: msiof: setup both (Playback/Capture) in the same time ASoC: renesas: msiof: tidyup DMAC stop timing ...
