Merge tag 'sound-fix-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai: "A collection of small fixes gathered since the previous update. ALSA core: - Regression fix for OSS PCM emulation ASoC: - Trivial fixes in reg bit mask ops, DAPM, DPCM and topology - Lots of fixes for Intel-based devices - Minor fixes for AMD, STM32, Qualcomm, Realtek Others: - Fixes for the bugs in mixer handling in HD-audio and ice1724 drivers that were caught by the recent kctl validator - New quirks for HD-audio and USB-audio Also this contains a fix for EDD firmware fix, which slipped from anyone's hands" * tag 'sound-fix-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (35 commits) ALSA: hda: Add driver blacklist ALSA: usb-audio: Add mixer workaround for TRX40 and co ALSA: hda/realtek - Add quirk for MSI GL63 ALSA: ice1724: Fix invalid access for enumerated ctl items ALSA: hda: Fix potential access overflow in beep helper ASoC: cs4270: pull reset GPIO low then high ALSA: hda/realtek - Add HP new mute led supported for ALC236 ALSA: hda/realtek - Add supported new mute Led for HP ASoC: rt5645: Add platform-data for Medion E1239T ASoC: Intel: bytcr_rt5640: Add quirk for MPMAN MPWIN895CL tablet ASoC: stm32: sai: Add missing cleanup ALSA: usb-audio: Add registration quirk for Kingston HyperX Cloud Alpha S ASoC: Intel: atom: Fix uninitialized variable compiler warning ASoC: Intel: atom: Check drv->lock is locked in sst_fill_and_send_cmd_unlocked ASoC: Intel: atom: Take the drv->lock mutex before calling sst_send_slot_map() ASoC: SOF: Turn "firmware boot complete" message into a dbg message ALSA: usb-audio: Add Pioneer DJ DJM-250MK2 quirk ALSA: pcm: oss: Fix regression by buffer overflow fix (again) ALSA: pcm: oss: Fix regression by buffer overflow fix edd: Use scnprintf() for avoiding potential buffer overflow ...
