i just updated my sparse to the newest -
so i'm using sparse 0.4.4

make ARCH=arm C=1  CF="-Wsparse-all"
and i still get all the warnings.

That is not the latest version of sparse. I'm not sure when sparse was
updated, but I have the git version which shows v0.5.0-51-ga53cea28f0db

Stephen, is this something you insist on?
i think the patch can stay as it is.
please let me know, as i wouldn't like this issue to block the entire patch
