For consistency with other reference counting APIs in the kernel, add drm_gem_object_get() and drm_gem_object_put(), as well as an unlocked variant of the latter, to reference count GEM buffer objects. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for the DRM subsystem-wide conversion is extended to account for these new helpers.
