In any case sparse gives a lot of false positives for this particular warning, so adding lines of code to try to shut up sparse for every single false positive seems to be a losing proposition. I'll note that these sorts of bugs are much more easily picked up using lockdep in any case, so we're probably better of just ignoring these sorts of warnings. Better to let the 0day kernel tester warn for new sparse warnings, instead of trying to drive sparse warnings down to zero.
