Re: ASUS G752VS Touchpad does not work

[Chris Chiu <chiu@endlessm.com>]

Hi KT,
    We user kernel version 4.8 when test the G752VSK but it should
work at 4.10 too. I'll verify that later. And yes, there's no ELAN
interrupt at all from the bug report. I would suggest to have the DSDT
for further analysis.
