This patch adds the support for the configuration of the keyboard backlight on supported Dell laptops. With this patch it is possible to set: * keyboard backlight level * timeout after which the backlight will be automatically turned off * input activity triggers (keyboard, touchpad, mouse) that enable the backlight * ambient light settings The settings are exposed via /sys/class/leds/dell::kbd_backlight/ The code is based on the newly released documentation by Dell in the libsmbios project.
