+Subject: [PATCH 360/726] spi: spidev: Restore loading from Device Tree
+
+As happens occasionally, an upstream change has once again prevented
+spidev from being loaded via Device Tree. We now need "spidev" to be
+included in the new spi_device_id list, otherwise although the
+spidev driver gets loaded no /dev/spidev*.* entries will appear.
