Subject: drm/udl: limit modes to the sku pixel limits.
From: Dave Airlie <[email protected]>
commit 3a75885848996baab5276ff37ebf7295c3c753f0 upstream.
Otherwise when X starts we commonly get a black screen scanning
out nothing, its wierd dpms on/off from userspace brings it back,
With this on F18, multi-seat works again with my 1920x1200 monitor
which is above the sku limit for the device I have.
