Huh, TIL, thank you.

See my comment in the other mail about the overlay. Generally, functions
of the form "screen->driver->..." are specific to the kernel module in
question, and we're not able to upstream the code specific to the vendor
kernel for various reasons. It may be a good idea to stub out the
corresponding routines in pan_drm.c, but that's up to Rob and Tomeu.
