1 | /* |
| 2 | * HID driver for Xin-Mo devices, currently only the Dual Arcade controller. | |
| 3 | * Fixes the negative axis event values (the devices sends -2) to match the | |
| 4 | * logical axis minimum of the HID report descriptor (the report announces | |
| 5 | * -1). It is needed because hid-input discards out of bounds values. | |
| 6 | * (This module is based on "hid-saitek" and "hid-lg".) | |
