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.
@param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
EFI_COMPONENT_NAME_PROTOCOL instance.
@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 DriverName[out] A pointer to the Unicode string to return.
This Unicode string is the name of the
driver specified by This in the language
specified by Language.
@retval EFI_SUCCESS The Unicode string for the Driver specified by
This and the language specified by Language was
returned in DriverName.
@retval EFI_INVALID_PARAMETER Language is NULL.
@retval EFI_INVALID_PARAMETER DriverName is NULL.

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
