@@ -15,8 +15,6 @@ The following FN keys are ignored by the kernel without this driver:
 - FN-F1 (LG control panel)   - Generates F15
 - FN-F5 (Touchpad toggle)    - Generates F21
 - FN-F6 (Airplane mode)      - Generates RFKILL
-- FN-F8 (Keyboard backlight) - Generates F16.
-  This key also changes keyboard backlight mode.
 - FN-F9 (Reader mode)        - Generates F14
 
 The rest of the FN keys work without a need for a special driver.
