ALSA: hda - Fix VIA output-path init for VT2002P/1802/1812
For VT2002P, VT1802 and VT1812 codecs, the original activate_output_path() function can't initialize output and hp path correctly, since mixers connected to output pin widgets are not considered. So modify the activate_output_path() function to satisify this kind of codec. Signed-off-by: Lydia Wang <lydiawang@viatech.com.cn> Signed-off-by: Takashi Iwai <tiwai@suse.de>
