ALSA: hda - Fix ThinkPad T410[s] docking station line-out

Browse source 
On the docking station for the Lenovo T410 and T410s, the line-out 
doesn't work. The trouble seems to be that it generates a plug event, 
but then doesn't report that the jack is connected. So automute mutes 
the jack when you plug something into it. The following patch (next 
message) fixes it.
