Let me check what you mean by that.  I hope you mean that the drm core,
drm helpers and drivers are individually responsible for dropping any
refcount that they obtain on any object.

In other words, if the drm core takes a refcount on object X, then the
DRM core must be the code base which drops that refcount.
