3.16.83-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Parav Pandit <parav@xxxxxxxxxxxx>
commit 89f988d93c62384758b19323c886db917a80c371 upstream.
Current code device add sequence is:
ib_register_device()
ib_mad_init()
init_sriov_init()
register_netdev_notifier()
Therefore, the remove sequence should be,
unregister_netdev_notifier()
close_sriov()
mad_cleanup()
ib_unregister_device()
However it is not above.
Hence, make do above remove sequence.
