CVE-2022-49151

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

can: mcba_usb: properly check endpoint type

Syzbot reported warning in usbsubmiturb() 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.

Fail log:
