Having looked at it again I changed my mind and decided it'll be more
consistent with the rest of the code if this comment remains above the
function after all.

My rationale is it is the only function for OxSemi Tornado devices still
without an introductory comment, the other functions have their internals
documented solely within their leading comments, and last but not least it
is obvious what the comment refers to, especially as the function is so
small (as to fit even in an 80x24 character glass TTY device).

I have posted v2 with your other suggestions applied. Thank you for your
review.

Maciej
