The ThinkPad can connect to more than one flat pannel display using the
external VGA or DVI output, which we may be able to control over DCC
someday.
Also, Lenovo may introduce a ThinkPad with more than one internal LCD
screen in the future. Or we could have LCD gadgets from ibm with
backlights connected to the ThinkPad...
This patch renames the main backlight device from "ibm" to
"thinkpad_builtin_screen", which is far more descriptive and future-proof.
Maybe the backlight devices refering to the built-in screen of laptops
should even be renamed to just "builtin_screen" on all of the drivers?
Please comment.
