This is the language of the driver 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.
DriverName - A pointer to the Unicode string to return. This Unicode string

specified by Language.
Returns:
EFI_SUCCESS - The Unicode string for the Driver specified by This
and the language specified by Language was returned
in DriverName.

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.
