Merge tag 'sound-fix-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai...

Pull sound fixes from Takashi Iwai:
 "A collection of small fixes for rc1.

  The only (LOC-wise) dominant change was ASoC Qualcomm fix, but most of
  it was merely a code shuffling.

  Another significant change here is for ALSA PCM core; it received a
  revert and a series of fixes for PCM auto-silencing where it caused a
  regression in the previous PR for rc1.

  Others are all small: ASoC Intel fixes, various quirks for ASoC AMD,
  HD-audio and USB-audio, the continued legacy emu10k1 code cleanup, and
  some documentation updates"
