860 * FUNCTION: AcpiNsValidateHandle
861 *
862 * PARAMETERS: Handle - Handle to be validated and typecast to a
863 * namespace node.
864 *
865 * RETURN: A pointer to a namespace node
866 *
867 * DESCRIPTION: Convert a namespace handle to a namespace node. Handles special
868 * cases for the root node.
869 *
870 * NOTE: Real integer handles would allow for more verification
871 * and keep all pointers within this subsystem - however this introduces
872 * more overhead and has not been necessary to this point. Drivers
873 * holding handles are typically notified before a node becomes invalid
874 * due to a table unload.
