Linus,

please pull sound fixes for v5.3-rc1 from:

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/sound-fix-5.3-rc1

The topmost commit is 4914da2fb0c89205790503f20dfdde854f3afdd8

----------------------------------------------------------------

sound fixes for 5.3-rc1

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

----------------------------------------------------------------
