Preparations are being made to replace acpi_driver with more generic struct platform_driver, which doesn't contain notify callback. Furthermore as of now handlers are being called indirectly through acpi_notify_device(), which decreases performance. Call acpi_device_install_event_handler() at the end of .add callback. Call acpi_device_remove_event_handler() at the beginning of .remove callback. Change arguments passed to the notify callback to match with what's required by acpi_install_event_handler().
