4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx> commit 57a95b41869b8f0d1949c24df2a9dac1ca7082ee upstream. ELAN0611 touchpad uses elan_i2c as its driver. It can be found on Lenovo ideapad 320-15IKB. So add it to ACPI table to enable the touchpad. [Ido Adiv <idoad123@xxxxxxxxx> reports that the same ACPI ID is used for Elan touchpad in ideapad 520].
