Remove all links of the subdev's media entity after internal_ops 'unregistered' call and right before unregistering the entity from a media device. It is assumed here that an unregistered (orphan) media entity cannot have links to other entities registered to a media device. It is also assumed the media links should be created/removed with the media graph's mutex held. The above implies that the caller of v4l2_device_unregister_subdev() must not hold the graph's mutex.
