I'm guessing this is really line 1020 at the top of set_ether_config(),
in the current kernel.  Because line 1050 has nothing to do with status_ep.

And I'm assuming that's 51 lines later, the "on error..." path.
As we know, no errors happen hence all error paths work Just Fine.  ;)

Another way to put this diagnosis is that the same test needs to
be used in both places, else it's overkill in one of them.
