InitFreeDeviceCallback rule (kmdf)
The InitFreeDeviceCallback rule specifies that a driver must call WdfDeviceInitFree if the driver encounters an error while it initializes a new framework device object, and if the driver received the WDFDEVICE_INIT structure from a call to WdfControlDeviceInitAllocate.
Driver model: KMDF
