Subject[PATCH 22/93] USB: keyspan: fix bogus array index
Date
3.5.7.15 -stable review patch.  If anyone has any objections, please let me know.

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

From: Johan Hovold <jhovold@gmail.com>

commit a07088098a650267b2eda689538133a324b9523f upstream.

The outcont_endpoints array was indexed using the port minor number
(which can be greater than the array size) rather than the device port
number.
