SubjectApplied "ASoC: sprd: Allow the MCDT driver to build into modules" to the asoc tree
The patch

ASoC: sprd: Allow the MCDT driver to build into modules

has been applied to the asoc tree at

All being well this means that it will be integrated into the linux-next

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
