From a8ef43b995fcd4c92edbf9492ac0378f8dc2441a Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 14 Mar 2017 08:08:36 +0100 Subject: mtd: when creating bitflips the offset has to be page aligned mtd_peb_create_bitflips() assumes the offset is page aligned. Enforce this and in the nand_bitlfip command print a warning if it's not aligned.
