Subject: RDMA/core: Follow correct unregister order between sysfs and cgroup
X-Git-Tag: v4.20-rc1~110^2~196
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c715a39541bb399eb03d728a996b224d90ce1336;p=thirdparty%2Fkernel%2Fstable.git

RDMA/core: Follow correct unregister order between sysfs and cgroup

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.
