From 27a030e8729255b2068f35c1cd609b532b263311 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Tue, 30 Nov 2021 11:24:43 +0000 Subject: [PATCH] mtd: dataflash: Add device-tree SPI IDs 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.
