Subject: ipv4: remove useless codes in ipmr_device_event()
X-Git-Tag: v3.3-rc1~182^2~412
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e92036a6516d07f61d4c214970a35ff05b919c25;p=platform%2Fkernel%2Flinux-stable.git

ipv4: remove useless codes in ipmr_device_event()

Commit 7dc00c82 added a 'notify' parameter for vif_delete() to
distinguish whether to unregister the device.

When notify=1 means we does not need to unregister the device,
so calling unregister_netdevice_many is useless.
