+                 specified by Language.

+  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 a three character ISO 639-2 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.
