Request dma channel from specific dma controller instead of generic
dma controller list, otherwise, may get the wrong dma controller
if there are multi dma controllers such as i.MX8MP.

Thanks!
[1/1] ASoC: fsl_asrc_dma: request dma channel from specific controller
commit: ee427ea4f12672e5d7874abaa634ddee0ff2bb97
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
