+ in DriverName.
+ EFI_INVALID_PARAMETER - Language is NULL.
+ EFI_INVALID_PARAMETER - DriverName is NULL.

+ 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.
+ 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.
