Subject: [PATCH] Add BTN_TOOL_BUTTONS to input.h
We "borrowed" BTN_TOOL_FINGER from input/mouse to pass tablet
buttons to the user land. This has not been an issue since
tablet was not considered as a mouse replacement. With the
introduction of hybrid digitizer and touch devices, the tool
type is causing confusion. A new tool type is due for the
well-being of future input device drivers.
