Subject[PATCH AUTOSEL 4.19 099/205] RDMA/core: Follow correct unregister order between sysfs and cgroup
Date
From: Parav Pandit <parav@mellanox.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.
