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, Mark

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").
