[PATCH] HID: magicmouse: Correct report range of major / minor axes

From: Yufeng Shen
Date: Fri Jun 22 2012 - 12:39:20 EST


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.
