Signed-off-by: Athul Raj Kollareth <krathul3152@gmail.com>
---
Changes in v3:
    - Revert all changes to drm_gem_objects_lookup()
    - Use drm_device as suggested in [1]. 
Changes in v2:
    - Change drm_gem_objects_lookup() to take a drm_device* argument.
    - Make appropriate changes to all calls of drm_gem_objects_lookup().

IIRC we shouldn't additionally report OOM errors as there will be
already lot of messages when we hit this

remove extra line and please run checkpatch.pl as it should catch that

also consider declaring variables in reverse-xmas-tree order
