Yes, annoyingly I accidentally it 'u' instead of 'y' in vi which
lower-cased the entire function, and didn't realise before sending the
patch as a theoretical solution to Romain. After build-testing it locally
I did notice it. I would've thought that Romain would've build-tested
before sending out his patch set and would've fixed it up... I didn't
have time to properly fix up my patch (essentially would've ment
redoing the edits from scratch to ensure that it was correct.) Still
don't have time to do that. Sorry.
