4.14-stable review patch. If anyone has any objections, please let me know.

From: Boris Brezillon boris.brezillon@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.
