I didn't just submit the patch because Sparse warns about it.  I
submitted the patch because of the coding style preference that led to
the Sparse warning.

Also, if this really *shouldn't* form part of the kernel style, then the
kernel should use -Wno-do-while with -Wall, or should stop using -Wall.

That said, I don't care all that much about the patch, so I won't push
further for it one way or another.
