From c4fc1956fa31003bfbe4f597e359d751568e2954 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Fri, 29 Apr 2016 15:42:25 +0200 Subject: [PATCH] EDAC: i7core, sb_edac: Don't return NOTIFY_BAD from mce_decoder callback Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it. E.g. neither of them had even bothered to check the type of the error to see if it was a memory error before the return NOTIFY_BAD.
