From 293b915fd9bebf33cdc906516fb28d54649a25ac Mon Sep 17 00:00:00 2001 From: Oscar Campos Date: Tue, 18 Jul 2017 17:20:36 -0700 Subject: Input: trackpoint - assume 3 buttons when buttons detection fails 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.
