If the length is 0, just\nskip the message and go on to the next one.\n\nThis has been fixed in the kvaser_usb driver in the past in commit\n0c73772cd2b8 (\"can: kvaser_usb: leaf: Fix potential infinite loop in\ncommand parsers\"), so there must be some broken devices out there like\nthis somewhere.",
