From 47e3a5edc6538d66e470aaed3b7c57255cb37ca1 Mon Sep 17 00:00:00 2001 From: Paul Donohue Date: Tue, 3 Jan 2017 10:39:28 -0800 Subject: [PATCH] Input: ALPS - fix TrackStick Y axis handling for SS5 hardware A minus character was lost in commit 23fce365, causing the Y axis to be inverted for SS5 TrackStick events. (Pushing the TrackStick up caused the pointer to move down, and vice versa.) Restore the lost minus.
