Thanks for the PR -- not sure why this was closed, but I took a quick look and perhaps it was because it was incomplete (Makefile changes are missing)?

Also, I don't think the template should have LLVM=1 as the default or things like M= and -C handled automatically. The commands are intentionally kept close to what you do in-tree. The idea of this repository is to have a basic template that showcases that there is little difference w.r.t. a C out-of-tree module (apart from the requirements as explained in the README), rather than to build a convenient, full-fledged framework here over time. For that, there are better templates/projects/approaches out there.

Finally, for future patches/PRs you may send, I would recommend describing your changes, splitting them, etc. I would recommend reading, for instance, https://docs.kernel.org/process/submitting-patches.html. Those are good practices, even outside the Linux kernel.
