It's a RH specific issue. The upstream code has a different definition of module_init(), thus no such an error would occur.
Note that I'm fine to apply the patch, it's a trivial change. But you need to give the clear reason why to apply it. In this case, it's no fault of the upstream code. But if it would make someone's life a bit easier, it's OK to apply such a change.
That being said, please resubmit the patch with a more explanation.
thanks,
Takashi

What compile error did you get?
