| Subject: [PATCH] RDMA/cma: add missed unregister_pernet_subsys in init failure |
| |
| commit 44a7b6759000ac51b92715579a7bba9e3f9245c2 upstream. |
| |
| 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") |
