From 10777de570016471fd929869c7830a7772893e39 Mon Sep 17 00:00:00 2001 From: Abhishek Sahu Date: Thu, 3 Aug 2017 17:56:39 +0200 Subject: mtd: nand: qcom: fix config error for BCH The configuration for BCH is not correct in the current driver. The ECC_CFG_ECC_DISABLE bit defines whether to enable or disable the BCH ECC in which 0x1 : BCH_DISABLED 0x0 : BCH_ENABLED But currently host->bch_enabled is being assigned to BCH_DISABLED.
