4 Subject: [PATCH 56/81] 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.
