As a result, it was claimed by hid-generic, which erroneously mapped the vendor telemetry collection (0xFF01) to an input node, translating the 1-Hz heartbeat timestamp into an endless loop of phantom KEY_BRIGHTNESSUP autorepeat events. Add the device to mt_devices[] with MT_CLS_DEFAULT so hid-multitouch claims the touchpad, eliminating the phantom input node. Tested on Honor MagicBook X14 Plus (FMI-76, AMD Ryzen 8845HS).
