Subject[PATCH 4.4 34/53] ALSA: hda - apply STAC_9200_DELL_M22 quirk for Dell Latitude D430
4.4-stable review patch.  If anyone has any objections, please let me know.


From: Alexander Tsoy <>

commit 1fc2e41f7af4572b07190f9dec28396b418e9a36 upstream.

This model is actually called 92XXM2-8 in Windows driver. But since pin
configs for M22 and M28 are identical, just reuse M22 quirk.

Fixes external microphone (tested) and probably docking station ports
(not tested).
