Re: [PATCH] powerpc/pseries: fix oops in hotplug memory notifier

During post-migration device tree updates, we can oops in
pseries_update_drconf_memory if the source device tree has an
ibm,dynamic-memory-v2 property and the destination has a
ibm,dynamic_memory (v1) property. The notifier processes an "update"
for the ibm,dynamic-memory property but it's really an add in this
scenario. So make sure the old property object is there before
dereferencing it.
