## Description

In the Linux kernel, the following vulnerability has been resolved:  can: mcba_usb: properly check endpoint type  Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. We should check that in endpoint is actually present to prevent this warning.  Found pipes are now saved to struct mcba_priv and code uses them directly instead of making pipes in place.
