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.
