Subject[PATCH 7/7][RFC] ASoC: rsnd: rsnd_write() / rsnd_bset() uses regmap _force_ function
Date
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Some R-Car sound requests picky register access which needs *force*
register write. To reduce complexity, this patch uses regmap force
function for all register access.
