@liOnux33 and I are trying to compile new kernel modules for Batocera 5.25, using the github repository https://github.com/batocera-linux/batocera.linux/
I was lucky enough last month to still have the 5.25_fixes branch and successfully managed to compile a module that matched the kernel in 5.25, but that branch is gone now.
Could you possibly add a batocera-5.25 tag so we can compile linux modules that match that version? That would be awesome! There are tags for all the other versions, so maybe that is just an oversight :-)
You can see our struggles here if anyone is interested: https://forum.batocera.org/public/d/3393-compile-a-linux-module-for-current-525-batocera
