Oh I see, I didn’t know that.

… or maybe just unpacking the kernel source so you have the makefile
snippet around?  Perhaps that’s enough?

I’m generally dubious about out-of-tree modules.  Given the way kernel
development works, we’re often talking about modules of poor quality, or
proprietary modules.  Do you know the reason this one is not in the main
tree?

Yes, sounds like a good idea.

Thanks,
Ludo’.
