[PATCH] USB: remove _some_ calls to usb_unlink_urb in misc/auerswald.c

   here's a more controversial one. Firstly, auerchain_unlink_urb:1180
   is a wrapper for usb_unlink_urb so i don't think we should change
   that. Secondly, auerswald_int_release returns an int which is the
   error code returned by usb_unlink_urb. usb_kill_urb is a void,
   however, so I've removed the error checking. For the sake of
   debugging, the dbg-line announcing the name of the function is
   probably enough.
