From: Derek Basehore <dbaseh...@chromium.org> [ Upstream commit 966334dfc472bdfa67bed864842943b19755d192 ]
This moves the wakeup increment for elan devices to the touch report. This prevents the drivers from incorrectly reporting a wakeup when the resume callback resets then device, which causes an interrupt to occur.
