From d24197907454b902908e025bce4b8bc677d3ba6b Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Mon, 1 May 2017 17:04:55 -0700 Subject: [PATCH] mtd: nand: samsung: warn about un-parseable ECC info We don't handle cases larger than 7. We probably shouldn't pretend we know the ECC step size in this case, and it's probably also good to WARN() like we do in many other similar cases.
