mceusb: fix NULL-deref at probe

Browse source

commit 03eb2a557e upstream.

Make sure to check for the required out endpoint to avoid dereferencing
a NULL-pointer in mce_request_packet should a malicious device lack such
an endpoint. Note that this path is hit during probe.

Fixes: 66e89522af ("V4L/DVB: IR: add mceusb IR receiver driver")
