Subject[PATCH] locking/lockdep: hide unused 'class' variable
Date
The usage is now hidden in an #ifdef, so we need to move
the variable itself in there as well to avoid this warning:

kernel/locking/lockdep_proc.c:203:21: error: unused variable 'class' [-Werror,-Wunused-variable]

Fixes: 68d41d8c94a3 ("locking/lockdep: Fix lock used or unused stats error")
