warning C28108: Variable holds an unexpected resource

The resource that the driver is using is in the expected C language type, but has a different semantic type.

The following code example generates this warning:

KeAcquireInStackSpinLock(spinLock, lockHandle);  
...  
KeReleaseSpinLock(spinLock, 0);  

The following code example avoids this warning:

KeAcquireInStackSpinLock(spinLock, lockHandle);  
...  
KeReleaseInStackSpinLock(lockHandle);
