The problem is that gcc is too smart. Switch does not handle a single
enumerator --- 'ed_success', very reasonable. It's handled before the
switch. Even if I add 'ed_success' case, it still report the warning.
So, I've worked this around by adding 'return' in default case. The change
is committed.
Thanks for the report,
