Rafael J. Wysocki d3c2872ae3 platform/chrome: Convert ChromeOS privacy-screen driver to platform
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 ChromeOS privacy-screen 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.
