Subject[PATCH 2/8] [media] v4l2-async: call registered_async after subdev registration
Date
V4L2 sub-devices might need to do initialization that depends on being
registered with a V4L2 device. As an example, sub-devices with Media
Controller support may need to register entities and create pad links.

Execute the registered_async callback after the sub-device has been
registered with the V4L2 device so the driver can do any needed init.
