intf
pointer to the usb_interface that is being deregistered
class_driver
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
call to usb_register_dev
(usually when the device is disconnected
from the system.)
This function also cleans up the devfs file for the usb device, if devfs is enabled, and removes the usb class device from the sysfs tree.
This should be called by all drivers that use the USB major number.
