Subject: ALSA: hda - Fix Dock Headphone on Thinkpad X250 seen as a Line Out
From: David Henningsson <david.henningsson@xxxxxxxxxxxxx>
commit ec56af67a10a0d82b79027878a81fce08d002d50 upstream.
Thinkpad X250, when attached to a dock, has two headphone outs but
no line out. Make sure we don't try to turn this into one headphone
and one line out (since that disables the headphone amp on the dock).
