ALSA: hda - Revisit output_path parsing in patch_via.c
Change the order of the output-path list in a way from the DAC to the target pin. Also now the list include the target pin, too. Together with this format change, simplify the arguments of parse_output_path() function, and fix the initialization in via_auto_init_output(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
