[alsa-devel] [PATCH 1/3] ASoC: rsnd: add rsnd_daidrv_get()

[Kuninori Morimoto]

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

rsnd priv has many parameters. On __rsnd_dai_probe() it uses
rsnd_rdai_get() to get rdai pointer, but is using priv->daidrv
directly to get daidrvhv, but it is confusable for reader.
This patch adds rsnd_daidrv_get() to get daidrv from priv.
Now reader can understand that rdai and daidrv are related.
