3.16.7-ckt8 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Hans de Goede <hdegoede@xxxxxxxxxx> commit e77a16355a29230b99bafe55834a8252e55308ec upstream. Backlight control through the native intel interface does not work properly on the Samsung 510R, where as using the acpi_video interface does work, add a quirk for this.
