Re: [libvirt] [PATCH 1/2] 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.
