Naming scheme is now: ei_device_<capability>_configure_<what>. So far the range is the only one where we had to deal with the same thing for two different capabilities and it's unlikely we'll have to have different keymaps for different capabilities. But still, let's do this now while it's still easy. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
