There could be a new attribute file, or we could use a blank line
written to autosuspend_delay_ms for this purpose. Either way, the
result would be to call pm_runtime_suspend. If the device is idle,
merely awaiting the timer expiration for a scheduled suspend or
autosuspend, this would cause it to suspend immediately.
