From 9bfc3fde9c64320f7165560a64888fad09bc0fee Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Thu, 16 Aug 2018 17:30:03 +0200 Subject: [PATCH] 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.
