From: Greg Kroah-Hartman

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


From: Johan Hovold <jhovold@xxxxxxxxx>

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
