This patch will collide with Andrew's _IOCTL_ naming change, but its a
fairly simple thing to resolve.

Sumit: If you're comfortable resolving the collision, please queue
with the rest of the recent changes for drm-misc-next.
Otherwise, I'm happy to submit the resolution I tested with here
afterwards. Let me know.

thanks
