From 028a7b6d3d9fa2cc41d76d45575345cca8d00a4c Mon Sep 17 00:00:00 2001 From: Dave Peterson Date: Sun, 26 Mar 2006 01:38:47 -0800 Subject: [PATCH] [PATCH] EDAC: edac_mc_add_mc fix [2/2] This is part 2 of a 2-part patch set. Fix edac_mc_add_mc() so it cleans up properly if call to edac_create_sysfs_mci_device() fails. Signed-off-by: David S.
