From 12197bf21c26e23053fa6223f3a731a965542986 Mon Sep 17 00:00:00 2001 From: Romain Izard Date: Wed, 13 Jan 2016 17:34:13 +0100 Subject: [PATCH] mtd: atmel_nand: Do not warn on bitflips When using multi-bit ECC, it is normal for the NAND Flash driver to correct bit errors during the life of the product. Those errors will only be cleared once a threshold has been reached, and corrections can occur regularly before this. Use only dev_dbg and not dev_info to report the bitflips, to keep the system log clean when everything works correctly.
