Which exact file is that? I didn't change the % modifiers for any of
the data types, or at least I sure shouldn't have, if so, that's a bug
on my side.

Thanks for testing, I'll queue these up, and if you can tell me which
sysfs file is different, I'll verify the code conversion again, but I
just reviewed it and can't seem to find anything.
