I never saw this warning. (Andrew, I'm still unable to fetch your current -mm tree, is there some place other than kernel.org? So the patch is done on top of 3.1-rc3). I guess this warrning is from p = flex_array_get(fa, i); ?

Moreover, flex_array_free calls for kfree which support NULL argument so it's natural to make this one NULL capable as well.
