From: Dave Airlie <airlied@redhat.com>
Since Matthew's efi/vga changes on non-EFI machines we were failing
to tell the vgaarb/switcheroo what the default device was, this
sets the default device in the quirk if none has been set before.
This fixes the switcheroo on my T410s.
[hpa: please ack to put this on top of the other patches in my -next tree].
