From 63c8331b826ad5f21cb0175308099f18d5fe526a Mon Sep 17 00:00:00 2001

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.
