Right now, is impossible for battery hook callbacks to access instance-specific data, forcing most drivers to provide some sort of global state. This however is difficult for drivers which can be instantiated multiple times and/or are hotplug-capable. Pass a pointer to the battery hook to those callbacks for usage with container_of().
