From: Jason Gerecke <jason.gerecke@xxxxxxxxx>
The Bluetooth reports from the 2nd-gen Intuos Pro have separate bits for
indicating if the tip or eraser is in contact with the tablet. At the
moment, only the tip contact bit controls the state of the BTN_TOUCH
event. This prevents the eraser from working as expected. This commit
changes the driver to send BTN_TOUCH whenever either the tip or eraser
contact bit is set.
