From 703e148875c838c430312da592d7ab3681ab5c81 Mon Sep 17 00:00:00 2001 From: Clinton Sprain Date: Wed, 26 Mar 2014 14:10:43 -0700 Subject: [PATCH] Input: appletouch - dial back fuzz setting Let's dial back the default fuzz setting for most devices using this driver, based on values from user feedback from forums and bug reports.
