Asynchronous sub-device registration helper for camera sensor drivers
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
:c:func:`v4l2_async_register_subdev_sensor` is a helper function for
sensor drivers registering their own async sub-device, but it also registers a
notifier and further registers async sub-devices for lens and flash devices
found in firmware. The notifier for the sub-device is unregistered with the
async sub-device.
