Input: pegasus-notetaker - check pipe type when probing Fix WARNING in pegasus_open/usb_submit_urb Syzbot bug: https://syzkaller.appspot.com/bug?id=bbc107584dcf3262253ce93183e51f3612aaeb13 Warning raised because pegasus_driver submits transfer request for bogus URB (pipe type does not match endpoint type). Add sanity check at probe time for pipe value extracted from endpoint descriptor. Probe will fail if sanity check fails.
