Build fails on Ubuntu 22.04 kernel 6.1.0

Hi,

Using the latest clone from the repository, I get the make.log file in attach. Please ignore version number, it was just the latest clone using the instructions at https://mrk.sh/linux/displaylink/fix-displaylink-kernel6.0/

Thanks!

I have a similar issue, where it seems to be a weird thing with how gcc compiles files. I was able to get it to compile perfectly on my previous install, but after my new one, evdi just refuses to compile. I'll put my make output below:
