dmesg showing 4.15.9-300.fc27.x86_64 boot, suspend, resume sequence with errors on resume

Description of problem:
Since upgrading my Fedora 27 kernel to 4.15.7, the mouse pointer on my Thinkpad t460p laptop is always non-responsive after resuming from suspend. I also tried 4.15.9 with same results.

NB I am using the TrackPoint, and have the TrackPad disabled.

This a regression from 4.14.x series of kernels, where the mouse worked fine after suspend, so I have dropped back to using kernel-4.14.18-300.fc27.x86_64 to avoid the problem.

There are various suspicious looking errors in kernel dmesg when resuming from suspend  - I will attach the full dmesg log to this bug

Version-Release number of selected component (if applicable):
kernel-4.15.7-300.fc27.x86_64
kernel-4.15.9-300.fc27.x86_64


How reproducible:
Always

Steps to Reproduce:
1. Boot 4.15.7 kernel until GDM login screen is ready
2. Press power button to trigger suspend to RAM
3. Wait for suspend to fully complete
4. Press power button again to trigger wakeup from suspend
5. Try to mouse the mouse using the TrackPoint

Actual results:
