+  An empty function to pass error checking of CreateEventEx ().
+
+  This empty function ensures that EVT_NOTIFY_SIGNAL_ALL is error
+  checked correctly since it is now mapped into CreateEventEx() in UEFI 2.0.
+
+  @param  Event                 Event whose notification function is being invoked.
+  @param  Context               The pointer to the notification function's context,
+                                which is implementation-dependent.
