The patch

   ASoC: SOF: enable sync_write in hdac_bus

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,

Subject: [PATCH] ASoC: SOF: enable sync_write in hdac_bus

Align SOF HDA implementation with snd-hda-intel driver and enable
sync_write flag for all supported Intel platforms in SOF. When set,
a sync is issued after each verb write.

Sync after write has helped to overcome intermittent delays in
system resume flow on Intel Coffee Lake systems, and most recently
probe errors related to the HDMI codec on Ice Lake systems.

Matches the snd-hda-intel driver change done in commit 2756d9143aa5
("ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips").
