----------------------------
-What: Support for lcd_switch and display_get in asus-laptop driver
-When: March 2010
-Why: These two features use non-standard interfaces. There are the
- only features that really need multiple path to guess what's
- the right method name on a specific laptop.
-
- Removing them will allow to remove a lot of code an significantly
- clean the drivers.
-
- This will affect the backlight code which won't be able to know
- if the backlight is on or off. The platform display file will also be
- write only (like the one in eeepc-laptop).
-
- This should'nt affect a lot of user because they usually know
- when their display is on or off.
