I'd rather see the table used as relying on the fallback path via the spi_match_id table
is fragile as two tables may not have equivalent entries in the long run.
Entry missing in the spi_driver.driver structure.
Bonus points for adding the match data to the of table and making them all pointers
there and in spi_device_id table + using spi_get_device_match_data()
