From 126b67b8d26f6623d199aa59279f2e3243f2144c Mon Sep 17 00:00:00 2001 From: Doug Thompson Date: Mon, 3 Aug 2009 12:37:06 +0200 Subject: amd64_edac: fix ECC checking On the good path of BIOS enabled ECC and no override, the value returned is 1 by omission and thus is deemed failing by the probe-function. Allow proper module initialization by clearing the retval explicitly.
