Hi,

I just ran into this while building other things against today's linux.git.

For the !CONFIG_PROVE_LOCKING case, the "class" variable is left unused.
Rather than tease apart the functionality in lockdep_stats_show(), where
class is used to increment up to 15 local variables, this patch merely
adds yet another ifdef to fix the build warning.

I'll leave it to a larger cleanup effort (which is probably not
worth the churn, actually) to avoid all of the ifdef slicing up
of these routines.
