Subject: [PATCH] Input: xpad - validate USB endpoint type during probe

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.
