[PATCH] ASoC: rsnd: don't use private_value on rsnd_kctrl_new()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Current rsnd kctrl is using both .private_value (for rsnd_kctrl_cfg)
and .private_data (for rsnd_mod) on snd_kcontrol.
But only 1 private data (= rsnd_kctrl_cfg) can be enough if it has
rsnd_mod pointer.
This patch doesn't use private_value.
