Basically move from

CL_INLINE void
cl_spinlock_acquire(
                IN           cl_spinlock_t* const       p_spinlock )
{
                KIRQL irql = KeGetCurrentIrql();
                CL_ASSERT( p_spinlock );

                if (irql == DISPATCH_LEVEL) {
                                KeAcquireSpinLockAtDpcLevel( &p_spinlock->lock );
                                p_spinlock->irql = irql;
                }
                else
                                KeAcquireSpinLock( &p_spinlock->lock, &p_spinlock->irql );
}

To

CL_INLINE void
cl_spinlock_acquire(
                IN           cl_spinlock_t* const       p_spinlock )
{
                CL_ASSERT( p_spinlock );
                KeAcquireSpinLock( &p_spinlock->lock, &p_spinlock->irql );
}
