[git pull] drm fixes

[Dave Airlie]

Slight update to fix a regression in one of the memory corruption fixes, 
we have another memory corruption myself/Keith are trying to track down, 
but laptops with 1.8" disks are defeating us, but its only in a rare 
unload case and may have been around for a while so it can probably live 
in -next and go in via stable.
