  returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
  by This does not support the language specified by Language,
  then EFI_UNSUPPORTED is returned.

  @param  This[in]              A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or

  Routine Description:
    Retrieves a Unicode string that is the user readable name of the controller
    that is being managed by an EFI Driver.

  Arguments:
    This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
    ControllerHandle - The handle of a controller that the driver specified by
                       This is managing.  This handle specifies the controller
                       whose name is to be returned.
    ChildHandle      - The handle of the child controller to retrieve the name
                       of.  This is an optional parameter that may be NULL.  It
                       will be NULL for device drivers.  It will also be NULL
                       for a bus drivers that wish to retrieve the name of the
                       bus controller.  It will not be NULL for a bus driver
                       that wishes to retrieve the name of a child controller.
    Language         - A pointer to RFC3066 language identifier.
                       This is the language of the controller name
                       that that the caller is requesting, and it must match one
                       of the languages specified in SupportedLanguages.  The
                       number of languages supported by a driver is up to the
                       driver writer.
    ControllerName   - A pointer to the Unicode string to return.  This Unicode
                       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.

  Returns:
    EFI_SUCCESS           - The Unicode string for the user readable name in the
                            language specified by Language for the driver
                            specified by This was returned in DriverName.
    EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
    EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid
                            EFI_HANDLE.
    EFI_INVALID_PARAMETER - Language is NULL.
    EFI_INVALID_PARAMETER - ControllerName is NULL.
    EFI_UNSUPPORTED       - The driver specified by This is not currently
                            managing the controller specified by
                            ControllerHandle and ChildHandle.
    EFI_UNSUPPORTED       - The driver specified by This does not support the
                            language specified by Language.

/**
  Retrieves a Unicode string that is the user readable name of the controller
  that is being managed by a driver.

  This function retrieves the user readable name of the controller specified by
  ControllerHandle and ChildHandle in the form of a Unicode string. If the
  driver specified by This has a user readable name in the language specified by
  Language, then a pointer to the controller name is returned in ControllerName,
  and EFI_SUCCESS is returned.  If the driver specified by This is not currently
  managing the controller specified by ControllerHandle and ChildHandle,
  then EFI_UNSUPPORTED is returned.  If the driver specified by This does not
  support the language specified by Language, then EFI_UNSUPPORTED is returned.

  @param  This[in]              A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
                                EFI_COMPONENT_NAME_PROTOCOL instance.

  @param  ControllerHandle[in]  The handle of a controller that the driver
                                specified by This is managing.  This handle
                                specifies the controller whose name is to be
                                returned.

  @param  ChildHandle[in]       The handle of the child controller to retrieve
                                the name of.  This is an optional parameter that
                                may be NULL.  It will be NULL for device
                                drivers.  It will also be NULL for a bus drivers
                                that wish to retrieve the name of the bus
                                controller.  It will not be NULL for a bus
                                driver that wishes to retrieve the name of a
                                child controller.

  @param  Language[in]          A pointer to a Null-terminated ASCII string
                                array indicating the language.  This is the
                                language of the driver name that the caller is
                                requesting, and it must match one of the
                                languages specified in SupportedLanguages. The
                                number of languages supported by a driver is up
                                to the driver writer. Language is specified in
                                RFC 3066 or ISO 639-2 language code format.

  @param  ControllerName[out]   A pointer to the Unicode string to return.
                                This Unicode 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.

  @retval EFI_SUCCESS           The Unicode string for the user readable name in
                                the language specified by Language for the
                                driver specified by This was returned in
                                DriverName.

  @retval EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.

  @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
                                EFI_HANDLE.

  @retval EFI_INVALID_PARAMETER Language is NULL.

  @retval EFI_INVALID_PARAMETER ControllerName is NULL.

  @retval EFI_UNSUPPORTED       The driver specified by This is not currently
                                managing the controller specified by
                                ControllerHandle and ChildHandle.

  @retval EFI_UNSUPPORTED       The driver specified by This does not support
                                the language specified by Language.
