Merge tag 'sound-fix-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

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

   - The optimization of PM resume with HD-audio HDMI codecs, which
     eventually work around weird issues

   - A correction of Intel Icelake HDMI audio code

   - Quirks for Dell machines with Realtek HD-audio codecs

   - The fix for too long sequencer write stall that was spotted by
     syzkaller

   - A few trivial cleanups reported by coccinelle"
