Replace the DRM_* logging macros used in gem helper files with the appropriate
ones specified in /include/drm/drm_print.h.

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().

Replace the DRM_* logging macros used in gem helper files with the appropriate
ones specified in /include/drm/drm_print.h.

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().

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

also consider declaring variables in reverse-xmas-tree order

Replace the DRM_* logging macros used in gem helper files with the
appropriate ones specified in /include/drm/drm_print.h.

Changes in v4:
    - Some codestyle corrections.
    - Remove OOM error logging in drm_gem_init().

Changes in v3:
    - Revert all changes to drm_gem_objects_lookup()
    - Use drm_device as suggested in the discussion [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().
