If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 2d283ede59869159f4bb84ae689258c5caffce54 Mon Sep 17 00:00:00 2001 From: Roger Quadros <rogerq@xxxxxx> Date: Thu, 30 Mar 2017 10:37:50 +0300 Subject: mtd: nand: omap2: Fix partition creation via cmdline mtdparts From: Roger Quadros <rogerq@xxxxxx> commit 2d283ede59869159f4bb84ae689258c5caffce54 upstream. commit c9711ec5250b ("mtd: nand: omap: Clean up device tree support") caused the parent device name to be changed from "omap2-nand.0" to "<base address>.nand" (e.g. 30000000.nand on omap3 platforms). This caused mtd->name to be changed as well. This breaks partition creation via mtdparts passed by u-boot as it uses "omap2-nand.0" for the mtd-id. Fix this by explicitly setting the mtd->name to "omap2-nand.<CS number>" if it isn't already set by nand_set_flash_node(). CS number is the NAND controller instance ID.
