Subject: [PATCH 3.18 08/19] Input: trackpoint - assume 3 buttons when buttons detection fails

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

------------------

From: Oscar Campos <oscar.campos@...ber.fsf.org>

commit 293b915fd9bebf33cdc906516fb28d54649a25ac upstream.

Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
this makes the middle button of the trackpoint to not being recogized.
As I don't believe there is any trackpoint with less than 3 buttons this
patch just assumes three buttons when the extended button information
read fails.
