Hi Michael,
FYI, there are new sparse warnings show up in
tree: git://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git master
head: 864499449f256e32815575a9b860267ebefa6d70
commit: 864499449f256e32815575a9b860267ebefa6d70 [6/6] tg3: Fix sparse warnings.
It's interesting that the patch actually eliminated all known sparse
warnings on that file. Perhaps that enables sparse to progress more
so as to find more types of problems? :)
