Back in October 2003 Arnaldo commited some fixes prior to 2.6 for some
leaking info to userspace in the usb drivers:
The corresponding changes have not been commited to 2.4, or included in
the previous sparse fixes. So I've assigned them CAN-2004-0685 (for 2.4
only, as they were fixed before 2.6.0). Treat as public.
