ACPI: video: Add dev argument for backlight_device_register
This patch set adds generic abstract layer support for acpi video driver to have generic user interface to control backlight and output switch control by leveraging the existing backlight sysfs class driver, and by adding a new video output sysfs class driver. This patch: Add dev argument for backlight_device_register to link the class device to real device object. The platform specific driver should find a way to get the real device object for their video device.
