Brown-paper bag time, the patch didn't compile due to missing parenthesis.
I really need to get a new powerpc machine to test on, haven't had one
since both my g3 and g4 laptops died.
Problem was caught by the kbuild test robot.
The below patch is a corrected version of the original, I could
probably provide an incremental one if that's better.
