Coding style cleanups are just part of life in the Linux kernel, and
while they make life a bit harder for developers by conflicting with
pending patches, I think they are viewed nonetheless as a win by the
Linux kernel developer community in order to promote readability and
long term maintainability by more than just the original developer(s).

So I have no problem with these or other similar coding style cleanups
to any of my code - I'm not ashamed to admit I botched the coding style
in the first place ;)
