The patch
ASoC: Intel: Skylake: Add flag to check to register FE dais from topology
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: Intel: Skylake: Add flag to check to register FE dais
from topology
Since FE dais can come from topology, split the FE dais from existing
dai array so that FE dais need not be registered if they come from
topology. Add use_tplg_pcm flag to check whether FE dais will be
registered from topology during dai driver component registration.
