I don't see bug on my machine. Are you sure it's not already fixed in 
a different way in linux-next?

It's a possibility.

Basically I have a v3.10-rc3 kernel and I did:

`git checkout next/master -- scripts`

I assumed some extra checking appeared in the scripts directory, so I
just fixed the warnings and sent out a patch.

This is also part of my other patch to ux500_read_asicid that
Linus just applied, but we could take yours for 3.10 if he thinks
it's important.

We don't need two patches conflicting about such small
things, so I'll drop this in favor of your patch.
