usb_get_dev(9)
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.
