Subject: mtd: nand: qcom: fix config error for BCH
From: Abhishek Sahu <absahu@codeaurora.org>
commit 10777de570016471fd929869c7830a7772893e39 upstream.
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.
