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).

This is one of fixes I had in mind (and asked for testing in bugzilla kernel.org report). One drawback by this is that the auto-mute *between* the headphones won't work like before. If one has expected it, then this can be seen as a regression.
Another fix was to change this as a proper line-out. This will keep the current auto-mute behavior.
OTOH, dealing both jacks equally is also not bad, per se.
