/*
* HID driver for Xin-Mo devices, currently only the Dual Arcade controller.
* Fixes the negative axis event values (the devices sends -2) to match the
* logical axis minimum of the HID report descriptor (the report announces
* -1). It is needed because hid-input discards out of bounds values.
* (This module is based on "hid-saitek" and "hid-lg".)
