Handler	The SMI handler.
CallerAddress	The address of the module who registers the SMI handler.
Context	The context of the SMI handler. For the SmmChildDispatch protocol, the Context must match the one defined for SmmChildDispatch protocol.

EFI_STATUS EFIAPI SmiHandlerProfileUnregisterHandler	(	IN EFI_GUID *	HandlerGuid,
		IN EFI_SMM_HANDLER_ENTRY_POINT2	Handler,
		IN VOID *Context	OPTIONAL,
		IN UINTN ContextSize	OPTIONAL
	)

This function is called by SmmChildDispatcher module to report an existing SMI handler is unregistered, to SmmCore.

Parameters

HandlerGuid	The GUID to identify the type of the handler. For the SmmChildDispatch protocol, the HandlerGuid must be the GUID of SmmChildDispatch protocol.
