I made this patch based on the following 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.
