Hi Klaas,

I don't yet have Fedora 37, but it is still possible to compile the 
drivers. After the 'make allyesconfig' I do the additional commands:

sed -i -r 's/(^CONFIG.*_RC.*=)./\1n/g' v4l/.config
sed -i -r 's/(^CONFIG.*_IR.*=)./\1n/g' v4l/.config
sed -i -r 's/(^CONFIG_VIDEO_TDA1997X=)./\1n/g' v4l/.config
sed -i -r 's/(^CONFIG_VIDEO_TM6000.*=)./\1n/g' v4l/.config

This lets the TBS drivers build successfully on 6.0.9-100.fc35.x86_64. I 
just removed any modules that didn't compile and so far no critical 
module has failed. I don't know how long this method will keep working for.
