   ASoC: soc-pcm: add dpcm_create/remove_debugfs_state()

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.

Subject: [PATCH] ASoC: soc-pcm: add dpcm_create/remove_debugfs_state()

soc-pcm.c has implementation which depends on CONFIG_DEBUG_FS.
But, we don't want to have random #ifdef.
This patch adds dpcm_create/remove_debugfs_state() and care it.
