usb_autopm_set_interface — set a USB interface's autosuspend state
int usb_autopm_set_interface ( | struct usb_interface * intf); |
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).
