In all cases in which a struct acpi_driver is used for binding a driver to an ACPI device object, a corresponding platform device is created by the ACPI core and that device is regarded as a proper representation of underlying hardware. Accordingly, a struct platform_driver should be used by driver code to bind to that device. There are multiple reasons why drivers should not bind directly to ACPI device objects [1]. Overall, it is better to bind drivers to platform devices than to their ACPI companions, so convert the Apple Backlight ACPI driver to a platform one. While this is not expected to alter functionality, it changes sysfs layout and so it will be visible to user space.
