My main concern is #ifdef removal (thus expanding the removal message
also on QARM). I understand that drm2 code is very old, but it works, is
used, and have very minimal impact on other architectures or rest of
kernel. Within these conditions, I don't see single reason to remove (on
ARM) drm2 code in 13.
