From 892a8682f71910aa12647c5636ec5304225c9e0f Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Fri, 15 Mar 2019 15:14:30 +0100 Subject: [PATCH] mtd: add get/set of_node/flash_node helpers Linux commit 28b8b26b308 ("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.
