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

------------------

From: Johan Hovold <jhovold@gmail.com>

commit a26f009a070e840fadacb91013b2391ba7ab6cc2 upstream.

The register access to enable hardware flow control depends on the
device port number and not the port minor number.
