/* Define these structs and ioctls so this can compile against an old kernel
* that doesn't support these features yet. The kernel this code runs on
* must support it, but adding these here allows it to build elsewhere.
* Without these, uinput can't correctly support setting the axis ranges for
* absolute axes which is essential for simulated touch devices.
