Subject: [PATCH AUTOSEL 4.14 045/103] RDMA/core: Follow correct unregister order between sysfs and cgroup
From: Parav Pandit <parav@...lanox.com>
[ Upstream commit c715a39541bb399eb03d728a996b224d90ce1336 ]
During register_device() init sequence is,
(a) register with rdma cgroup followed by
(b) register with sysfs
Therefore, unregister_device() sequence should follow the reverse order.
