*sigh* Should be fixed in r327454. Thanks for reporting

I wonder if we can get clang to be more strict about
declarations/prototypes/etc to match gcc's expectations. I understand
that it's developers' responsibility to make sure that kernel
is GCC-buildable but if raising red flag for some of the cases
when compiling with clang reduced number of these breakages
that it'd be an improvement.
