While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct spi_device_id that replaces .driver_data by an anonymous union. Also adapt spacing and usage of commas to the most common style. This patch doesn't modify the compiled array, only its representation in source form benefits.
