Thinkpad T440s trackpad and trackpoint stop working after resume from suspend

[Sb]

Hi, this is a sporadic issue that sometimes appears, sometimes not. Usually once it starts happening it occurs on every suspend/resume cycle until the system is rebooted. The trackpad and the red trackpoint nub stop working after resume. This is on a Thinkpad T440s laptop currently running a fresh install of Ubuntu 20.04 with Gnome and no major modifications.

Usually the trackpad can be fixed by unloading/loading the `psmouse` module.

Thanks.
