Subject: ASUS G752VS Touchpad does not work

Hi KT Liao, Duson Lin,

A user reported that the touchpad on ASUS G752VS does not work [1], it's an ELAN touchapd.

I did the following change, the touchpad correctly loads elan-i2c instead of hid-multitouch, but it's still not working.

[KT] I check the touchpad of this model, it's MS precision touchpad.
It must use "hid-multitouch", not "elan-i2c".



Thanks.
