From: Chris Chiu <hidden>
Date: 2016-12-12 12:43:11
ROG means ASUS "Republic of Gamers" laptops. The input device info also represents itself as "ASASTeK COMPUTER INC. ROG MacroKey". It uses special HID_USAGE code for function keys. This commit remap the special code to standard keycode for function keys handling. It's verified on GL553VD/VE, GL753VD/VE.
