From 59d8570d4b61af8544fc295d5e83ab7c28294bb8 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Tue, 22 Mar 2016 03:52:07 +0100 Subject: [PATCH 56/91] 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.
