pointer to the usb_interface that is being deregistered
pointer to the usb_class_driver for this device
Used in conjunction with
usb_register_dev. This function is called
when the USB driver is finished with the minor numbers gotten from a
usb_register_dev (usually when the device is disconnected
from the system.)
This function also removes the usb class device from the sysfs tree.
This should be called by all drivers that use the USB major number.
