I did see your comment but did not include this in the v3 of the patchset. I leave it to others to deal with this part so the patchset are not postponed due to GPL discussions. Sam

In the quest to get rid of drmP.h move the newly added EXPORT_SYMBOL_FOR_TESTS_ONLY to drm_util.h. Fix the single user. Add a note to drmP.h to avoid further use of it.
