Descriptions

In the Linux kernel, the following vulnerability has been resolved:

Input: aiptek - properly check endpoint type

Syzbot reported warning in usb_submit_urb() which is caused by wrong
endpoint type. There was a check for the number of endpoints, but not
for the type of endpoint.

Fix it by replacing old desc.bNumEndpoints check with
usb_find_common_endpoints() helper for finding endpoints

Fail log:

usb 5-1: BOGUS urb xfer, pipe 1 != type 3
