From: Linus Walleij <linus.wall...@linaro.org>
[ Upstream commit 60cc7767b901dd1e3f70755c3d2505556ba487c2 ]
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.
