usb_autopm_set_interface — set a USB interface's autosuspend state
the usb_interface whose state should be set
This routine sets the autosuspend state of intf's device according to intf's usage counter, which the caller must have set previously. If the counter is <= 0, the device is autosuspended (if it isn't already suspended and if nothing else prevents the autosuspend). If the counter is > 0, the device is autoresumed (if it isn't already awake).
