 Let's back to the `queued_spin_lock` function. Assuming that we are the first one who tried to acquire the lock, the `val` will be zero and we will return from the `queued_spin_lock` function:
 
 ```C
-	val = atomic_cmpxchg_acquire(&lock-val, 0, _Q_LOCKED_VAL);
+	val = atomic_cmpxchg_acquire(&lock->val, 0, _Q_LOCKED_VAL);
 	if (likely(val == 0))
 		return;
