From 9ac7bd114e13628467c037066786775a357d91d6 Mon Sep 17 00:00:00 2001 From: Matjaz Hegedic Date: Fri, 10 Mar 2017 14:33:09 -0800 Subject: [PATCH] Input: elan_i2c - add ASUS EeeBook X205TA special touchpad fw commit 92ef6f97a66e580189a41a132d0f8a9f78d6ddce upstream. EeeBook X205TA is yet another ASUS device with a special touchpad firmware that needs to be accounted for during initialization, or else the touchpad will go into an invalid state upon suspend/resume. Adding the appropriate ic_type and product_id check fixes the problem.
