I tried your patch on an HP Elitebook, but with rather limited
success. Before, I was able to use the touchpad in limited fashion
(https://bugs.freedesktop.org/show_bug.cgi?id=100345). With your patch
(applied on top of 4.10), the touchpad no longer reacts at all.

That said, I didn't find a patch 2/2 anywhere.. is there something
missing?

Thanks,
-Nikolaus
