It might also be good to capture the same output from upstream
v4.13-rc1, since the touchpad does not work with that kernel. We can
then do a diff of the two.

touchscreen that worked in artful with 4.12 no longer works with 4.13

I have a Dell Venue 11 Pro 7139, and when I installed artful on it
(before release) it worked fine. Recently (over the xmas break I think
but I'm not sure; this is not a machine I intended to pay too much
attention to) the kernel moved from 4.12 to 4.13, and the touchscreen
has stopped working.
I _think_ the last kernel to work was 4.12.0-13. I haven't done any
sort of bisection though.
