The patch
ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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] ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type
A DAPM_DOUBLE control type can be used for dual channel mixer input
selectors / mute controls in one register, possibly toggling both
channels together.
The control is meant to be shared by 2 widgets, 1 for each channel,
such that the mixer control exposed to userspace remains a combined
stereo control.
