Name

usb_get_dev — increments the reference count of the usb device structure

Synopsis

struct usb_device * usb_get_dev (struct usb_device *  dev);

Arguments

dev

the device being referenced

Description

Each live reference to a device should 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_dev, in their disconnect methods.

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