commit 27a030e8729255b2068f35c1cd609b532b263311 upstream.
Commit 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_ids are
missing for the dataflash driver and the following warnings are now
seen.
WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,at45
WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,dataflash
Fix this by adding the necessary spi_device_ids.
