The commit e7bbb7acabf4 ("dmaengine: add peripheral configuration")
adds peripheral configuration for dma_slave_config.

This configuration is useful for some audio peripherals, for
example, the peripheral supports multi fifos, we can
let the DMA know which fifos are selected. So also add
this configuration for snd_dmaengine_dai_dma_data.

Thanks!

[1/1] ASoC: dmaengine_pcm: add peripheral configuration
      commit: 500c9f8c58a7c8cd5d9c1483569c046cfcfc47a4

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
