[alsa-devel] [PATCH 10/16] ASoC: rsnd: remove unsed rdai parameter from each function

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

Current rsnd driver's many functions requests struct rsnd_dai (= rdai), but, 1) we can get rdai from rsnd_io_to_rsnd(), 2) almost all rdai is not used. Let's remove these rdai.
