That's annoying, I thought I did build test the final changes.
However, there's a mistake in the Makefile meaning that it wasn't
building with no warning/error messages - it actually wasn't building
at all! Sorry about that Thierry.
I guess if you can build the driver, you've already fixed that?

After that change, I can see that you're absolutely correct:

Sorry for the fuss.
