Use usb_get_intf() and usb_put_intf() in order to update the reference
count of the usb interface structure.

This is quite pointless as the driver will be unbound from the interface
before interface is deleted.

From the documentation of usb_get_intf():

[quote]

Each live reference to a interface must be refcounted.

Drivers for USB interfaces should normally record such references in their 
probe() methods, when they bind to an interface, and release them by calling
usb_put_intf(), in their disconnect() methods.

Thanx
