Perhaps, but
1. Existing kernel style uses braces with single-statement
do-while.
2. Linus prefers (or at least preferred in October of 2006) braces
with single-statement do-while.

Good point; Sparse shouldn't warn about this by default. I've turned
that off in latest Sparse from Git, so you need to give -Wdo-while or
-Wall to get warnings about that. However, the kernel gives -Wall, so
you'll still see the warnings there.
