Wireless Adapter Driver with DKMS always fails on new kernel


I've been running my workstation with a wireless adapter RTL871X that needs an external driver (currently using this one). Once the driver is built/installed with dkms everything works well.

The problem occurs when I upgrade the kernel via normal dnf upgrade. I observe DKMS attempting to rebuild the module, but when my computer reboots it shows that the version magic is incorrect:

[ 5.562719] 8814au: version magic '5.0.6-200.fc29.x86_64 SMP mod_unload ' should be '5.0.7-200.fc29.x86_64 SMP mod_unload '

The only way to get wifi working again is to uninstall/reinstall the module using dkms. I've put this in a script on my home directory called, but obviously this is not the correct solution.

For completeness, here's my script:

#!/usr/bin/env bash

sudo dkms uninstall -m rtl8814au -v 4.3.21
sudo dkms install -m rtl8814au -v 4.3.21

This has been happening for months now, and doesn't seem to be tied to a specific Fedora version. From what I can ascertain the new module is being built with the old kernel sources. How do I fix this so my wifi works after a new kernel upgrade without this hacky workaround?
