[alsa-devel] Applied "Revert "ASoC: SOF: Force polling mode on CFL and CNL"" to the asoc tree

[Mark Brown <broonie@kernel.org>]

The patch

   Revert "ASoC: SOF: Force polling mode on CFL and CNL"

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

Subject: [PATCH] Revert "ASoC: SOF: Force polling mode on CFL and CNL"

This reverts commit 64ca9d9fcb3e3c86b1417e3d17a90b43dd660f81.

The workaround is no longer needed after configuring HDAC
bus with sync_write=1.
