SpinLockDpc rule (storport)
This rule verifies that a call to KeAcquireSpinLockRaiseToDpc is promptly followed by a call to KeReleaseSpinlock. If a driver calls KeAcquireSpinLock or KeAcquireSpinLockRaiseToDpc again prior to releasing the lock, it fails the rule. In addition, before exiting the dispatch or cancel routine, the driver must release the spin lock.
