From 3adde1f59195df2965f632e22b31f97fb371612f Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Sun, 8 Mar 2015 22:34:50 -0700 Subject: Input: synaptics - remove TOPBUTTONPAD property for Lenovos 2015 The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons" touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay! Instead of manually removing each of the new ones, or hoping that we know all the current ones, we can consider that the PNPIDs list that were given contains touchpads that have the trackstick buttons, either physically wired to them, or emulated with the top software button property. Thanks to the extra buttons capability in query $10, we can reliably detect the physical buttons from the software ones, and so we can remove the TOPBUTTONPAD property even if it was declared as such.
