Merge tag 'sound-fix-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "Here are last-minute fixes gathered before merge window close; a few
  fixes are for the core while the rest majority are driver fixes.

   - PCM locking annotation fixes and the possible self-lock fix

   - ASoC DPCM regression fixes with multi-CPU DAI

   - A fix for inconsistent resume from system-PM on USB-audio

   - Improved runtime-PM handling with multiple USB interfaces

   - Quirks for HD-audio and USB-audio

   - Hardened firmware handling in max98390 codec

   - A couple of fixes for meson"
