drm_open doesn't lock before increasing dev->open_count

is this a problem? before trying to submit a solution I wanted to make sure with the experts it seems open_count isn't locked and can cause problems and if it is a problem, and needs to be solved, should locking be done or is it better implemented with the (as I understand standard) kref? ht
