Subject: ALSA: hda - Store PCM parameters properly in HDMI open callback
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=639cef0eb6df05d5516520aa89b0c9fe62ee2d3b;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Store PCM parameters properly in HDMI open callback

In hdmi_pcm_open(), the evaluated PCM hw parameters are stored in
hinfo, but these aren't properly set back to the current runtime
record since these have been set beforehand in azx_pcm_open().
This patch fixes the behavior.
