Hi Greg,

I couldn't find the problem with this patch. Just in case I redo the patch
against the updated staging-testing and resent it. To test it I did:

 - run checkpatch
 - git apply --check
 - email it to myself and then 'git am' from mutt 
 - git log

I've just sent the patch. Please let me know if I missed something.

Thanks,

Gaston
