USB: reorganize urb->status use in usbmon
This patch (as978) reorganizes the way usbmon uses urb->status. It now accepts the status value as an argument. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
