Subject: ALSA: hda - fix headset mic problem for Dell machines with alc236
From: Hui Wang <hui.wang@xxxxxxxxxxxxx>
commit f265788c336979090ac80b9ae173aa817c4fe40d upstream.
We have several Dell laptops which use the codec alc236, the headset
mic can't work on these machines. Following the commit 736f20a70, we
add the pin cfg table to make the headset mic work.
