Subject: [PATCH 1/3] powerpc: numa: Remove double of_node_put in hot_add_node_scn_to_nid

From: Anton Blanchard <[email-masked]>

During memory hotplug testing, I got the following warning:

ERROR: Bad of_node_put() on /memory@0

of_node_release
kref_put
of_node_put
of_find_node_by_type
hot_add_node_scn_to_nid
hot_add_scn_to_nid
memory_add_physaddr_to_nid
...

of_find_node_by_type() loop does of_node_put for us so remove the
duplicate one inside the loop.
