3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit b5fd2a3e92ca5c8c1f3c20d31ac5daed3ec4d604 upstream.

Two tablets in this series support both pen and touch. One (Intuos S)
only supports pen. This patch also updates the driver to process wireless
devices that do not support touch interface.
