The interface argument is used just for retrieving the assigned device, which can be already found in line6->ifcdev. Drop them from the callbacks. Also, pass the usb id to private_init so that the driver can deal with it there. This is a preliminary work for the further cleanup to move the whole allocation into driver.c.
