This supersedes https://www.mail-archive.com/linux-media@vger.kernel.org/msg150027.html
based on feedback from Laurent:

and Sakari:

It actually makes the code a bit simpler in places compared to the v4, so
that's a good sign.

In this v5 I now check if a GRABBER device is a video or metadata device
(or both!) by checking device_caps.

Regards,
