SubjectRe: [PATCH 12/14] spi: spi-at91-usart: Make use of the defined 'struct of_device_id'

Is that the correct resolution? Isn't the proper thing to do simply
removing at91_usart_spi_dt_ids as the only way it will ever be probed is
through drivers/mfd/at91-usart.c and I would think matching the driver
name is enough.
