I think it is easiest if you post a v5, assuming everything that this series needs is now merged in the kernel. I'll pick it up.

I'll pick it up. Ok. There are comments in this thread which I haven't addressed yet. So I'll rebase on top of latest v4l-utils, address the comments and post v5. Tomi

Add client capabilities related hanges to include/linux/v4l2-subdev.h. This should be dropped when the v4l-utils kernel headers are updated to the version which contains client capabilities.
