4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Brezillon <boris.brezil...@bootlin.com>
commit 2b1b1b4ac716fd929a2d221bd4ade62263bed915 upstream.
get_sectorsize() was not using the appropriate macro to extract the
ECC sector size from the config cache, which led to buggy ECC when
using 1024 byte sectors.
Fixes: f88fc122cc34 ("mtd: nand: Cleanup/rework the atmel_nand driver")
