However, all the drivers call spi_master_put() in the error path if spi_register_master() fails. Thus we should call device_del() rather than device_unregister() before return error from spi_register_master(). This also makes all the spi_register_master() error handling consistent, because all other error paths of spi_register_master() expect drivers to call spi_master_put() if spi_register_master() fails.
