Could you please add your Signed-off-by: line?
(see linux/Documentation/SubmittingPatches)

There are a few nits, it would be nice if you could clean them up:
- the patch adds whitespace and end-of-line in a few places
- indentation is one tab, not 8 spaces

Please always start a new line after if/else.

Please don't add unnecessary braces. (I realize there are plenty of
those already but we don't want to add more. If you feel like doing more
of those cleanups please do it in a seperate patch.)

I don't think there's another way, so the FIXME should be removed.


Thanks,
