In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.
The patch was generated using the following coccinelle semantic patch:
// <smpl>

identifier _driver;

struct spi_driver _driver = {
	.driver = {
-		.bus = &spi_bus_type,
	},
};
