Subject: ALSA: hda - initialize channel counts correctly
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c0f3b21643487e2bbf8af534a33ffd2857e18fa1;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - initialize channel counts correctly

Even a single DAC can output two channels, so the channel count
is twice the number of DACs.
