You will need to convert your patch into proper hid_driver and
implement drv->input_mapping() method instead of overriding emitted
events. Then, once HID core is aware about proper mapping, normal
EVIOCGKEYCODE/EVIOCSKEYCODE will work and will allow adjusting
keymap from user space.

I think if you take drivers/hid/hid-belkin.c as a template the
conversion will take you no time.
