Subject: [PATCH 1/1] edac cell: fix incorrect edac_mode

From: Benjamin Herrenschmidt <benh@...nel.crashing.org>

The cell_edac driver is setting the edac_mode field of the
csrow's to an incorrect value, causing the sysfs show routine
for that field to go out of an array bound and Oopsing the kernel
when used.
