Applied "ASoC: soc-pcm: add dpcm_fe_dai_cleanup()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-pcm: add dpcm_fe_dai_cleanup()

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.

Subject: [PATCH] ASoC: soc-pcm: add dpcm_fe_dai_cleanup()

dpcm_fe_dai_close() and error case of dpcm_fe_dai_open()
need to do same cleanup operation.
To avoid duplicate code, this patch adds dpcm_fe_dai_cleanup()
and use it.
