[PATCH net-next 3/5] net: gemini: Allow multiple ports to instantiate

[linus.walleij@linaro.org (Linus Walleij)]

The code was not tested with two ports actually in use at
the same time. (I blame this on lack of actual hardware using
that feature.) Now after locating a system using both ports,
add necessary fix to make both ports come up.
