Currently logic for installing notifications from ACPI devices is
implemented using notify callback in struct acpi_driver. 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_device_install_event_handler().
