DeleteDevice rule (wdm)

The DeleteDevice rule specifies that drivers should not rely on the I/O Manager or PnP Manager to keep the DeviceObject alive after a call to IoDeleteDevice.

Drivers should call IoDeleteDevice after the lower driver has returned. This is the recommended behavior. This rule applies to FDO and FIDO drivers.

When handling an IRP_MN_REMOVE_DEVICE request, the driver should only call IoDeleteDevice after IoCallDriver or PoCallDriver have returned.
