[alsa-devel] [PATCH] ASoC: rsnd: add rsnd_kctrl_xxx() macro

Wed Oct 11 06:42:34 CEST 2017
From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>
Current CTU/MIX/DVC are directly using rsnd_kctrl_cfg_m/s to control
val etc, but it is difficult to read/understand.
And there was no uniformity in access method.
This patch adds new rsnd_kctrl_xxx() and implements uniformed access
method.
