Since these are part of the state now, I believe you also need to add a
drm_property_reference_blob() call in
__drm_atomic_helper_crtc_duplicate_state and a
drm_property_unreference_blob() call in
__drm_atomic_helper_crtc_destroy_state so that we properly
increment/decrement the reference count as the state gets
duplicated/destroyed.  I don't see that later in the series, so this
might be the best patch to add it to.
