The patch

   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

to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: soc-generic-dmaengine-pcm: Fix error handling

When dmaengine_pcm_request_chan_of() fails it should release
the previously acquired resources, which in this case is to
call kfree(pcm), so jump to the correct point in the error
path.
