+ This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
+ ControllerHandle - The handle of a controller that the driver specified by

+ of. This is an optional parameter that may be NULL. It

+ string is the name of the controller specified by
+ ControllerHandle and ChildHandle in the language specified
+ by Language from the point of view of the driver specified
+ by This.
