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.

A pointer to the interface with the incremented reference counter is returned.
