ALSA: hda - Fix line-in on Mac Mini Core2 Duo
BIOS on Mac Mini Core2 Duo sets both INPUT and OUTPUT pinctl bits to the line-in jack, and it confuses the driver as if it's a valid input. This patch adds the check of OUTPUT bit so that the driver fixes the invalid pin setup. Tested-by: Tino Keitel <tino.keitel@gmx.de> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
