When someone is sending a patch for inclusion, at the very minimum
I expect it to have been compiled, and preferably tested too. Doesn't
matter how small the change is, even a one-liner should go through that.

That said, I'm not a huge fan of changes like this. It completely
hides what is going on for someone reading the code, and it's not
like there's a win on code size for example. The only win seems to
be that driver writes can't mess it up, which is a nice benefit.
