Merge tag 'sound-fix-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull more sound updates from Takashi Iwai:
 "A few last-minute updates, most of them are the regression fixes:

   - AMD HD-audio HDMI runtime PM improvements

   - Fixes for HD-audio HDMI regressions wrt DP-MST

   - A regression fix for the previous aloop enhancement

   - A fix for a long-time problem in PCM OSS layer that was spotted by
     fuzzer now

   - A few HD-audio quirks"
