Isn't it trivial to verify it with the current v4l2 bindings? And
endpoint must have a 'remote-endpoint' property, and the endpoint on the
other end must have similar property, pointing in the first endpoint.
Anything else is an error.
I agree that it's easier to write bad links in the dts with
double-linking than with single-linking, but it's still trivial to
verify it in the kernel.
