Subject: ASoC: uda134x: fix bias level setup on initialization
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e4295b40ee64da20a3e31921745baba65e10ab36;p=openwrt%2Fstaging%2Fblogic.git

ASoC: uda134x: fix bias level setup on initialization

On initialization ADC/DAC are enabled only for UDA1341, that's why
bias_level shall be set to off explicitly, otherwise dapm is
misinformed about bias_level on startup.
