Thanks! I've queued it up in next/fixes-non-critical for linux-4.4
now, if you find something wrong later, we can revert or fix up.

There is no urgency for this one, especially since you still want to
test it, so no reason to put it in 4.3.

This was the last pre-2015 build warning for the ARM defconfigs
and allmodconfig, all remaining warnings are regressions or new
code, and I've submitted patches for those. Let's see if we can
get to a warning-free kernel build in 4.4.
