From 702df64053e440344ccb53035cb6959f17a97151 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 16 Apr 2012 15:09:46 -0300 Subject: [PATCH] i5000_edac: convert driver to use the new edac ABI The legacy edac ABI is going to be removed. Port the driver to use and benefit from the new API functionality.
