561 * Get the device ready for USB port or system standby and hibernation
563 * USB port and system standby are handled the same.
565 * When the system hibernates, the USB device is powered down and then
566 * up, so we don't really have to do much here, as it will be seen as
567 * a reconnect. Still for simplicity we consider this case the same as
568 * suspend, so that the device has a chance to do notify the base
569 * station (if connected).
571 * So at the end, the three cases require common handling.
573 * If at the time of this call the device's firmware is not loaded,
574 * nothing has to be done. Note we can be "loose" about not reading
575 * i2400m->updown under i2400m->init_mutex. If it happens to change
576 * inmediately, other parts of the call flow will fail and effectively
579 * If the firmware is loaded, we need to:
581 * - tell the device to go into host interface power save mode, wait
584 * This is quite more interesting than it is; we need to execute a
585 * command, but this time, we don't want the code in usb-{tx,rx}.c
586 * to call the usb_autopm_get/put_interface() barriers as it'd
587 * deadlock, so we need to decrement i2400mu->do_autopm, that acts
588 * as a poor man's semaphore. Ugly, but it works.
590 * As well, the device might refuse going to sleep for whichever
591 * reason. In this case we just fail. For system suspend/hibernate,
592 * we *can't* fail. We check PM_EVENT_AUTO to see if the
593 * suspend call comes from the USB stack or from the system and act
596 * - stop the notification endpoint polling
