    HID: Add driver to fix Speedlink VAD Cezanne support · 74bc6953
    Stefan Kriwanek authored
    Speedlink VAD Cezanne have a hardware bug that makes the cursor "jump" from one
    place to another every now and then. The issue are relative motion events
    erroneously reported by the device, each having a distance value of +256. This
    256 can in fact never occur due to real motion, therefore those events can
    safely be ignored.  The driver also drops useless EV_REL events with a value of
    0, that the device sends every time it sends an "real" EV_REL or EV_KEY event.
