Pushed with a small tweak, thanks!

I've removed this error message - if we fail, better return an error
code silently. At least your next patch is built a way that it will keep
iterating and executing this function.

We might as well print an error message if (!ENOTTY && !ENOTSUPP), but I
did not do this. I expect you to send a correction patch if you do not
like this :-)

Thanks!
