The patch
ASoC: topology: Add FE DAIs dynamically
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: topology: Add FE DAIs dynamically
Topology will create FE DAIs dynamically from the PCM objects,
and register them to the component.
A PCM topoplogy object describes a FE DAI and DAI link. Later
patch will add FE DAI links as well.
Change tplg load ops for DAI:
- Only process a DAI.
- Pass the DAI driver pointer to the component driver for
extra initialization.
