Oh, I missed we already had those calls. When adding the connector
support, I looked at struct v4l2_subdev_core_ops and didn't find a
callback that fit but didn't notice we already had a .registered()
in struct struct v4l2_subdev_internal_ops. Sorry about that...

Yes, those can be used indeed. I'll post patches using that instead
and removing the .registered_async callback since as you said isn't
really needed.
