From 5535856f0e31aa6abf4cda11b5c53c0f164680f0 Mon Sep 17 00:00:00 2001 From: John Ferlan Date: Thu, 1 Mar 2018 07:08:32 -0500 Subject: [PATCH] conf: Fix crash in virDomainDefCompatibleDevice Commit id 'edae027c' blindly assumed that the passed @oldDev parameter would not be NULL when calling virDomainDeviceGetInfo; however, commit id 'b6a264e8' passed NULL for AttachDevice callers under the premise that there wouldn't be a device to check/update against.
