The patch
ASoC: Intel: Skylake: Use set_tdm_slot to set the dma channel
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

DMA channel(stream tag) used by the HDA link need to programmed in codec so that codec receives packet from the link associated with the same channel.
DMA channel is allocated in link BE dai hw_params, the same needs to be set for the BE codec dai. Instead of using get/set dma_data(), use dai_ops snd_soc_dai_set_tdm_slot() to set the stream tag.
