4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cameron Gutman <aicommander@xxxxxxxxx>
commit 122d6a347329818419b032c5a1776e6b3866d9b9 upstream.
We should only see devices with interrupt endpoints. Ignore any other
endpoints that we find, so we don't send try to send them interrupt URBs
and trigger a WARN down in the USB stack.
