 126   Arguments:
 127     This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
 128     ControllerHandle - The handle of a controller that the driver specified by
 129                        This is managing.  This handle specifies the controller
 130                        whose name is to be returned.
 131     ChildHandle      - The handle of the child controller to retrieve the name
 132                        of.  This is an optional parameter that may be NULL.  It
 133                        will be NULL for device drivers.  It will also be NULL
 134                        for a bus drivers that wish to retrieve the name of the

 136                        that wishes to retrieve the name of a child controller.

 138                        identifier.  This is the language of the controller name
 139                        that that the caller is requesting, and it must match one

 142                        driver writer.
 143     ControllerName   - A pointer to the Unicode string to return.  This Unicode
 144                        string is the name of the controller specified by
 145                        ControllerHandle and ChildHandle in the language specified
 146                        by Language from the point of view of the driver specified

 152                             specified by This was returned in DriverName.

 155     EFI_INVALID_PARAMETER - Language is NULL.
 156     EFI_INVALID_PARAMETER - ControllerName is NULL.
 157     EFI_UNSUPPORTED       - The driver specified by This is not currently managing
