Merge tag 'sound-fix-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Just a collection of small fixes here: the most outstanding one is the
  re-application of USB-audio lowlatency support that was reverted in
  the previous PR. The rest are device-specific quirks/fixes, spelling
  fixes and a regression fix for the old intel8x0 driver"
