While this is pretty interesting abuse of the macros, please get rid
of it. I'm sure code will look better as a result.

Yup, and you can abuse xor operator too. Don't do that. I believe you
wanted to say:

+ return 0;

Just return ret; no need for goto. (Please fix globally).

Should turning off the led go to separate function?

Yeah, well, no.

This one is unrelated and not really an improvement.
