Yeah. Sorry about that. The kbuild-bot doesn't do much cross function
analysis (none for functions that are not inline). I saw that this
patch was old and could easily have checked it on my system which has
the cross function DB but I was in a rush. :/ My bad. Will try be a
more diligent person next time.
