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

2019-06-06 Thread Nathan Lynch
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
