    Subject[PATCH] HID: add multi-input quirk for NextWindow Touchscreen.
    These touchscreens are mounted onto HP TouchSmart and the Dell Studio One
    19. Without a quirk they report a wrong button set and the x/y coordinates
    through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's
    evdev driver).

    Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could
    only be performed on a model 1900.
