Without this change on v4.2 it is driven by i2c_hid, but behaves as a
regular mouse, so no absolute events, multitouch, tap to click etc. I
have not tried to use hid-multitouch with this touchpad, as I thought
hid-multitouch was a touchscreen driver. Is there any drawback in
having this supported by elan_i2c? Should I try a different approach?

No, that is fine, I was just checking. Applied, thank you.
