Subject: Input: xpad - validate USB endpoint type during probe

From: Cameron Gutman <[email protected]>

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.
