This supersedes https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg150027.html based on feedback from Laurent: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg150117.html and Sakari: https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg150129.html 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.
