Merge tag 'sound-7.3-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A collection of small fixes. Most of them are device-specific fixes
  while there are a few core fixes. The continued flux, but not too
  scaring yet. Some highlights below.

  ALSA Core:
   - Fix potential UAF after asynchronous card release
   - Fix a race condition in PCM timer initialization order

  USB-Audio:
   - Hardening fixes for issues reported by fuzzer for 6fire, bcd2000,
     and implicit FB packets
   - Fix double list addition in implicit FB handling
   - Quirks for AVerMedia GC553Pro and Behringer FCA1616

  HD-Audio:
   - Quirks / fixes for HP OmniBook 7, OMEN 15, and Victus 15 laptops

  ASoC:
   - Support for DAI link codec channel mask to avoid mismatches
   - Fix HDMI-codec channel status change report
   - Fixes for various codecs and platforms: Realtek rt712/rt721
     (calibration, reset fixes), Cirrus Logic (empty EFI variable
     validation, capture channel fixup), AMD ACP SoundWire (bounds
     checks, refactorings), ADAU1977 (OF match table support, SPI
     cleanups), ES8336 (Huawei Matebook B3-420 quirk), UX500 (macro
     fix)"
