I don't know to be honest, I just followed the pattern of all the other
pinctrl-sun?i-*.c files. But it sounds logical that this is needless

Looks like it got introduced when splitting up the driver:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-April/251712.html

Maybe there were plans to use separate modules some day. If not, we
should remove it from the other files as well I guess. Maxime, could
you please comment on that?

Jens
