insmod: ERROR: could not insert module build/force-remove-bootfb.ko: Invalid module format

Worked fine until today. I think there was a Fedora kernel update yesterday, maybe that broke it?

I'm on

Linux fedora.local 5.17.6-300.fc36.x86_64 #1 SMP PREEMPT Mon May 9 15:47:11 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

Error:

I rebuild the module and it's working now.

make clean
make
sudo ./remove.sh

For anyone else reading this and on Fedora: I have kernel-devel installed too.
