usb_get_intf — increments the reference count of the usb interface structure
struct usb_interface * usb_get_intf ( | struct usb_interface * | intf); |
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.
A pointer to the interface with the incremented reference counter is returned.
