   4 Subject: [PATCH 56/90] mtd: add get/set of_node/flash_node helpers
   5
   6 We are going to begin using the mtd->dev.of_node field for MTD device
   7 nodes, so let's add helpers for it. Also, we'll be making some
   8 conversions on spi_nor (and nand_chip eventually) too, so get that ready
   9 with their own helpers.
