I suppose that these warnings are false positives for the reasons explained in
my patch.

Furthermore, I found a commit by Fabio Aiuto <fabioaiuto83@gmail.com> that, as
far as I understand, do the same changes and that has been accepted by Greg K-
H and merged in his tree: b97fad10de387c09ae46f607955c7237afa96654. So, I
think there one reason more to suspect of false positives.

I'd appreciate comments on this topic.

Thanks,

Fabio
