    Subject[PATCH v3 05/13] HID: hid-multitouch: support arrays for the split of the touches in a report
    Date
    Win8 certification introduced the ability to transmit two X and two Y per
    touch. The specification precises that it must be used in an array.

    This test guarantees that we split the touches on the last element
    in this array.
