The check for DEFINE_SPINLOCK was spread throughout the source tree. If not defined we can just define it in inlucde/dahdi/kernel.h. Now include/dahdi/kernel.h is the only place that references SPIN_LOCK_UNLOCKED (which breaks lockdep checking if DEFINE_SPINLOCK is otherwise defined in the kernel).
