//  OsrCreateClose
//
//    This is the dispatch entry point for processing both IRP_MJ_CREATE
//    and IRP_MJ_CLOSE functions.  Since this is a simple device driver,
//    there's really nothing to do here by complete the requests with success.
//
//
//  INPUTS:
//
//      DeviceObject - Address of the DEVICE_OBJECT for our device.
//  
//      Irp - Address of the IRP representing the IRP_MJ_CREATE or IRP_MJ_CLOSE
//          call.
//
//  OUTPUTS:
//
//      None.
//
//  RETURNS:
//
//    STATUS_SUCCESS.   We never fail this function.        
//
//  IRQL:
//
//      This routine is called at IRQL PASSIVE_LEVEL.
