[alsa-devel] [PATCH][resend] ASoC: rsnd: merge snd_pcm_ops::open and snd_soc_dai_ops::startup
From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
Current rsnd driver has snd_pcm_ops::open and snd_soc_dai_ops::startup, but, these are called from soc_pcm_open in same time. This patch merge these into rsnd_soc_dai_startup()
