Could you move the MAINTAINERS change to a different patch? It would
make it easier to integrate separately.

Connectors shouldn't be registered in the bridge driver, they should
be registered by the kms driver after drm_dev_register is called.
The drm_connector_register_all() API is used for that.

This drm_bridge_enable() doesn't seem to serve any purpose here. It also
doesn't seem to make much sense to call drm_bridge_() funcs within a
bridge op itself.

Is there a reason why we register the interrupt handler here and not in
probe?
