Leaves info->drm_format unset.

drm_format_mod is unaligned. Should be avoided, otherwise the struct
layout is different on i386 and x86_64.
Patch 5/5 moves around this struct. Better have a separate patch
adding the structs and ioctls, order it before this one, so you don't
have to rename the stuff just added ...

Has alignment problems too.
