I need the driver rtl8821CU for my Odroid Wifi-module
Unfortunately, it is failing to build via dkms on Kernel 5.18.1
Here is my system info:
https://clbin.com/I8ybw
Here is the source for the driver:
I see that there is an issue open
Is there a simple fix to get the driver to build for me? Or is the only recourse to wait for the dev to fix the issue?
Any help is appreciated.
Is there a compatibility patch? If so, yes. If not,
Seems a bit selfish to keep it to yourself. 
I will share it obviously. 
where can I read and learn more about this?
A compatibility patch would be something like
https://aur.archlinux.org/cgit/aur.git/tree/kernel-5.18.patch?h=nvidia-390xx-utils
That is, a patch to add compatibility.
If one exists then getting the driver to build is easy. If one doesn’t exist then it needs to be written before the driver will compile.
I tried to build the driver for my Laptop running the LTS kernel just to confirm. It failed to build there too.
