[alsa-devel] [PATCH 1/1] ALSA: ASoC: add new param mux to dapm_mux_update_power

[Richard Zhao]

Function dapm_mux_update_power needs enum index mux and register mask value val
as parameters, but it only has a parameter val, and uses it as both val and mux.
snd_soc_test_bits(widget->codec, e->reg, mask, val) val is register mask here,
e->texts[val] but val should be enum index mux here.

This patch adds a new param mux to fix it.
