ALSA: hda - Fix headset mic detection problem for two Dell laptops
They uses the codec ALC255, and have the different pin cfg definition from the ones in the existing pin quirk table. Now adding them into the table to fix the problem. Cc: stable@vger.kernel.org Signed-off-by: Hui Wang <hui.wang@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
