[PATCH v2 1/8] [media] v4l: of: Correct v4l2_of_parse_endpoint() kernel-doc

[Javier Martinez Canillas]

The v4l2_of_parse_endpoint function kernel-doc says that the return value
is always 0. But that is not true since the function can fail and a error
negative code is returned on failure. So correct the kernel-doc to match.
