Subject: PROBLEM: Touchpad does not work after suspend on Lenovo X1 Carbon 6th

[1.] One line summary of the problem:
Touchpad does not work after suspend on Lenovo X1 Carbon 6th

[2.] Full description of the problem/report:
Touchpad and trackpoint are correctly detected and work perfectly fine
when the laptop powers up. After closing the lid, it goes into S3
suspend mode. After waking up, in most cases the touchpad and
trackpoint stop working. Sometimes one of them works, sometimes both,
seems very random. Tested on freshly compiled 5.7-rc3 kernel, same
thing seems to happen on older versions as well (including stable - I
tried Ubuntu 18.04, 20.04 and Fedora 31 and 32 with their built-in
kernels). Doing rmmod and modprobe on psmouse module once or twice
brings back the devices to life. dmesg shows some additional issues
when using the touchpad as well. I'm ready to test whatever fixes you
come up with, the laptop isn't currently being used, can be turned
into full time testing machine to finally fix this issue.

[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
Linux version 5.7.0-rc3 (maciej@...net) (gcc version 9.3.0 (Ubuntu
9.3.0-10ubuntu2), GNU ld (GNU Binutils for Ubuntu) 2.34) #1 SMP Fri

[8.7.] Other information that might be relevant to the problem
       (please look in /proc and include all information that you
       think to be relevant):
I attach the full dmesg after a few suspends and psmouse module
removals and insertions. Some detailed descriptions of what happens
when:
Laptop is powerered on: [   00.000000] - [   15.924274]
Xinput shows these input devices at this point:
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ Synaptics TM3288-011                        id=12    [slave  pointer  (2)]
⎜   ↳ TPPS/2 Elan TrackPoint                      id=13    [slave  pointer  (2)]
Close lid, suspend, wake up: [  251.222484] - [  256.281313]
Touchpad/trackpoint not working at this point; rmmod and modprobe
psmouse twice: [  328.251883] - [  354.249981]
Touchpad and trackpoint working now. Suspend and wake up again: [
587.807248] - [  592.830255]
After wakeup, touchpad working. Suspend again a few times, touchpad
and trackpoint seem to work in most cases.
Around [  778.483827] touchpad is working, but trackpoint is not
(buttons are integrated with trackpoint, so don't work either). xinput
returns:
⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ Synaptics TM3288-011                        id=12    [slave  pointer  (2)]
Around [ 1048.342982] issued rmmod and modprobe psmouse, everything
working again.
At the very bottom, dmesg seems to register some issues while using
the touchpad normally, mainly:
rmi4_f12 rmi4-02.fn12: Failed to read object data. Code: -6.
rmi4_physical rmi4-02: Failed to read irqs, code=-6

Please let me know what additional info you might need.
