[alsa-devel] [PATCH] ASoC: rsnd: need to call nolock_stop if nolock_start was failed

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

rsnd_dai_call() is counting the called number of start/stop functions.
nolock_stop should be called if nolock_start was failed.
Otherwise, nolock_start doesn't called in 2nd play.
This patch solved this issue.
