  Retrieves a Unicode string that is the user readable name of the driver.

  This function retrieves the user readable name of a driver 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 driver name is
  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.

/**
  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[in]  This              A pointer to the EFI_COMPONENT_NAME2_PROTOCOL
                                or EFI_COMPONENT_NAME_PROTOCOL instance.
  @param[in]  ControllerHandle  The handle of a controller that the driver
                                specified by This is managing.  This handle
                                specifies the controller whose name is to be

  @param[in]  ChildHandle       The handle of the child controller to retrieve
                                the name of.  This is an optional parameter

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