I think there is some whitespace damage on this patch? At least I 
couldn't apply it as is :/  Also the lack of a space after the final 
comma on the line above looks suspicious too... have you tried running 
scripts/checkpatch.pl on the resulting diffs?

Apart from the whitespace issues, the basic patch looks fine though.
