The patch
ASoC: Revert "ASoC: soc-generic-dmaengine-pcm: Fix error handling"
has been applied to the asoc tree at
https://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

This reverts commit f91b1e73ccde71d4bc69ae10d475196df38844ab.
As explained by Lars-Peter Clausen:
"This creates a resource leak. dmaengine_pcm_request_chan_of() requests bothtransmit and receive channels. It might return with an error if one of them fails, but the other one succeeded. In this case we need to call dmaengine_pcm_release_chan() to free the requested channel"
So revert the commit.
