After using that patched kernel for 2 days, it's also solves the suspend
freezing problem, i am able to close the lid and open it without removing the
i2c_hid.
Also theres no random freezes/slowdowns like on the 4.14-rc7 kernel.

Oliver & Hans, thank you!
After reverting that patch and applying the other one + resolving the
conflicts, i can confirm it works on 4.17.0-rc6 (chuwi lapbook air).
Movement, tap, scroll, left and right button.

Tried it on my machine, it does not solve the touchpad problems on Chuwi
Lapbook air, i think it has a different touchpad than what that fix
solves.

Someone mentioned, if you blacklist the i2c_hid driver, then the
resume/suspend starts working without deep freeze. (atleast on Chuwi
Lapbook Air)

I can't test the touchpad on 4.16, since it wont get up from suspend state.
Tried it on 4.16-rc1 and 4.16-rc2 and it was the same. Resume from suspend
worked on 4.15 but not on 4.16 and also on 4.15-rc9 i was able to get a
half-working (cursor movement/tap, but no left/right buttons) touchpad
Okay, i created a respinned ubuntu 16.04 iso with a mainline
kernel(4.15.0rc9)
So if i just push the suspend button instead of closing the lid, i can wake up
the device.
And the touchpad starts working after waking up.
Movement works
Tap works
Left/Right button not
Looks like this issue is
Well, i tried that one but i cant get back the device from suspended
state.
Also checked if the touchpad hardware works, on windows 10, it was
working until the latest insider update, they just broke it somehow.
I'm gonna somehow try to check that suspend/resume.

Maybe, the device is similar to ours, but they were able to get some
movement from the touchpad and we dont.
I collected some logs (sorry, i dont have ubuntu now, i tried again with
mainline kernel).

Hi, maybe this helps something
Someone mentioned on other forums that maybe Hans de Goede's patch (
https://patchwork.kernel.org/patch/10046575/ ) could fix that problem,
but unfortunately it does not, i compiled a kernel which contains his fix but
it does not solve the problem.
