Extending the patch from November 2014 with two more

models that also ship the Elantech touchpad and don't work with
crc_disabled.

Applied, thank you.

However I am not happy with the direction we are going - the fact that

if we could detect whether we need CRC or not by querying the touchpad
somehow. Elantech folks, could you help us here?

Thanks!
