As of commit 5186421cbfe2 ("drm: Introduce epoch counter to drm_connector") the drm_get_edid() function calls drm_connector_update_edid_property() for us. There's no reason for us to call it again.

His suggestion to do this more broadly is a good idea but this series is probably a bit ambitious already so I would suggest that be taken up separately.
