Thanks. Since the HID USAGE page is not found in the report descriptor, I can only quirk this in process_events function instead of input_mapping. I need some more information. Could u help me test the kernel in https://people.canonical.com/~mschiu77/lp1927545/v4 and give me the dmesg output which includes the Fn+F4 keypressing. Thanks.
