    Subject[PATCH] HID: magicmouse: Correct report range of major / minor axes
    Date
    In patch "HID: magicmouse: Adjust major / minor axes to scale",
    touch_major and touch_minor axes are scaled by a factor of
    four when reported but the max touch_major/minor is not scaled
    accordingly. This patch scales the max touch_major/minor to
    be consistent with the reported value.
