How many modules do you have here? What are their names? We have one module, named "Bosch SMI240 driver". Any problem here? > + > +static const struct spi_device_id smi240_spi_id[] = { { "smi240", 0 > +}, {} }; Don't wrap it.

You introduce now warnings. Did not get your point, why we introduce now warnings here ? Best regards, Jianping Shen
