Subject: [PATCH 4.4 02/59] RDMA/cma: add missed unregister_pernet_subsys in init failure

From: Chuhong Yuan <hslester96@...il.com>

[ Upstream commit 44a7b6759000ac51b92715579a7bba9e3f9245c2 ]

The driver forgets to call unregister_pernet_subsys() in the error path
of cma_init().
Add the missed call to fix it.

Fixes: 4be74b42a6d0 ("IB/cma: Separate port allocation to network namespaces")
