[Bug] linuxPackages_cachyos-lto.xone fails to compile

[apt-install-coffee]

What happens?

when building a system with
config.boot.kernelPackages = pkgs.linuxPackages_cachyos-lto;
and
config.hardware.xone.enable = true;

build errors which were otherwise fixed here are present.

when looking through the build artifacts, it seems none of the patches specified in the package have been applied.

What is expected to happen?

xone should have been pached to work with 6.12, and build alongside the cachyos-lto kernel.

If possible, please attach logs
