+Subject: [PATCH 63/66] mtd: add get/set of_node/flash_node helpers
+
+We are going to begin using the mtd->dev.of_node field for MTD device
+nodes, so let's add helpers for it. Also, we'll be making some
+conversions on spi_nor (and nand_chip eventually) too, so get that ready
+with their own helpers.
