[Lenovo ThinkPad T14] Mouse / trackpad buttons sometimes don't work after waking up from suspend

[Bernd Rinn]

After waking up from suspend, the trackpad (and, if connected mouse) buttons sometimes don't work anymore. Only a reboot fixes it.

Note that I move the mouse pointer and use the keyboard, just the trackpad / mouse buttons stop working.

I have observed this bug both with Wayland and with X11.

1. Release: Ubuntu 22.04
2. Version: gnome-shell 42.2-0ubuntu0.2
3. What I expect to happen: the trackpad and mouse buttons work always after waking up from suspend.
4. What happened instead: the trackpad and mouse buttons do not work about every third time after waking up from suspend.

Here are some additional information:
- When the error occurs, not only do the keys of the trackpad of the T14 stop to work, but also any USB mouse that is connected shows the same problem.
- The errors seems to mostly occur when the laptop is not connected to any external device (monintor, USB devices) at the time of wake-up.
