Note that some array entries contains NULL so changing the code
that way you are returning NULL in some cases while before
was never NULL. Simply modifying the string solve the gcc issue
without this regression. Snir was working in the same issue but
you arrived first with a patch.
Potentially this change the reply to a public API. Maybe to avoid
potentially having an "unknown" channel we could use "UNKNOWN"
or "Unknown" ?
