++ * control the order. They can be used to turn off the screen and input
++ * devices that are not used for wakeup.
++ * Suspend handlers are called in low to high level order, resume handlers are
++ * called in the opposite order. If, when calling register_early_suspend,
++ * the suspend handlers have already been called without a matching call to the
++ * resume handlers, the suspend handler will be called directly from
++ * register_early_suspend. This direct call can violate the normal level order.
