[alsa-devel] [PATCH 0/3] ASoC: rsnd: fixup SWSP bit for SSI parent
Hi Mark Renesas BSP team Yokoyama-san noticed that SSI need to care about SWSP bit if SSI is working as parent, otherwise, it might have noise when recording. These patches solve this issue.

From: Kuninori Morimoto <kuninori.morimoto.gx@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.
