Al Viro said that, until sparse is improved, the only solution would
be to work around in the rather ugly way as posted in the original
patches.  As Frederic and hpa preferred not having the workaround and
there were only three instances in the kernel tree, I just left them
alone so sparse warning will trigger spuriously on those three
locations.

Thanks.
