NAME
       usb_get_intf - increments the reference count of the usb interface structure

SYNOPSIS
       struct usb_interface * usb_get_intf(struct usb_interface * intf);

ARGUMENTS
       intf
	   the interface being referenced

DESCRIPTION
       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.

RETURN
       A pointer to the interface with the incremented reference counter.
