To size the problem:
- there are about 3434 references to DRM_DEBUG_* in all the drm code, all drivers.
- there are 413 references to DRM_DEBUG_* in the drm core code, only 66 of
   them are related to connectors.
- there are 62 references to DRM_ERR* and 7 references to DRM_INFO in
   the drm core programs.

I meant I can make two patches:
 1 - this one with the change to CONNECTOR:id:name (29 changes)
 2 - a new and bigger patch to change 413 + 62 + 7 references to DRM_{DEBUG,ERR,INFO}
     in the drm core programs.

The second patch will be ready in a few days.

Is it a good plan ? or can it be improved ?

Best regards,
Claudio Suarez.
