Subject: drivers/base/node.c: switch to register_hotmemory_notifier()
X-Git-Tag: v3.10-rc1~183^2~37
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6e259e7dc482d4d5e2701259ddc85ffebd957502;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

drivers/base/node.c: switch to register_hotmemory_notifier()

Squishes a warning which my change to hotplug_memory_notifier() added.

I want to keep that warning, because it is punishment for failnig to check
the hotplug_memory_notifier() return value.
