4.18-stable review patch. If anyone has any objections, please let me know.

[ 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.
