- Subject: [PATCH 06/33] 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.
