The Parfait (version 2.1.0) static code analysis tool found the following NULL pointer dereference problem. - drivers/gpu/drm/drm_drv.c Any calls to drm_minor_get_slot() could result in the return of a NULL pointer when an invalid DRM device type is encountered. The return of NULL was removed with BUG() from drm_minor_get_slot().
