[alsa-devel] [PATCH 2/2][RFC] ASoC: add for_each_rtd_codec_dai() macro

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

ALSA SoC snd_soc_pcm_runtime has snd_soc_dai array for codec_dai. To be more readable code, this patch adds new for_each_rtd_codec_dai() macro, and replace existing code to it.
