+Subject: ALSA: hda - Add GPIO1 control at muting with HP laptops
+Patch-mainline: 
+References: bnc#515266,bnc#522764
+
+HP laptops with AD1984A codecs (at least mobile models) need to set
+GPIO1 appropriately to indicate the mute state.  The BIOS checks this
+bit to judge whether the mute on or off is sent via F8 key.
+Without changing this bit, the BIOS can be confused and may toggle
+the mute wrongly.
