ALSA: hda/conexant - Don't set HP pin-control bit unconditionally
Some output pins on Conexant chips have no HP control bit, but the auto-parser initializes these pins unconditionally with PIN_HP. Check the pin-capability and avoid the HP bit if not supported. Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
