Subject: ASoC: soc-dai: add snd_soc_dai_hw_free()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=846faaed9df7899e74311db3aec0a41a2f6bc345;p=linux.git

ASoC: soc-dai: add snd_soc_dai_hw_free()

Current ALSA SoC is directly using dai->driver->ops->xxx,
thus, it has deep nested bracket, and it makes code unreadable.
This patch adds new snd_soc_dai_hw_free() and use it.
