I still have much to learn on the subsystem.. what I did to test it was trying out this command:
media-ctl -d platform:vidtv -p
Media controller API version 5.11.0

Media device information
------------------------
driver          vidtv
model           vidtv
serial
bus info        platform:vidtv
hw revision     0x0
driver version  5.11.0


I was under the impression that this was enough to show everything was in order with the patch.
