Just want to provide you some quick feedback from the user's
perspective...

I tested this patch set on my somewhat hacked together laptop - I have
a Lenovo T440p with the touchpad replaced with a "top button pad" from
a T450 or similar.

With this patch set (and using the psmouse.synaptics_intertouch=1
option), the touchpad is found and used via RMI4/SMBUS, and the PS2
passthrough to the trackpoint does work. Passing the buttons presses
from the top buttons to the trackpoint device doesn't work - my
understanding is the code for this isn't included here?

The touchpad cursor movement (and scrolling, etc.) is so much smoother
than with the PS2 interface of this touchpad model... I'm glad these
patches are getting closer to complete!

Calvin.
