ALSA: hda - Add support of dock-mic detection to Conexant auto-parser
In addition to the normal external mic jack, check also the mic jack on a docking-station as well, and select the input source appropriately. The similar functionality was already implemented in patch_sigmatel.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
