> When the device is registered via OF, the OF table is used to match the
> driver instead of the SPI device ID table, but the entries in the later
> are used as aliasses to load the module if the driver was not built-in.
> This is because the SPI core always reports an SPI module alias instead
> of an OF one, but that could change so it's better to always export it.
