From: Ben Hutchings
Date: Sun Jun 16 2013 - 18:28:02 EST


3.2.47-rc1 review patch. If anyone has any objections, please let me know.

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

From: Johan Hovold <jhovold@xxxxxxxxx>

commit a26f009a070e840fadacb91013b2391ba7ab6cc2 upstream.

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