The same change should be done for the ibv_alloc_pd() call.

   635         if (!cma_dev->pd)
   636                 cma_dev->pd = ibv_alloc_pd(cma_dev->verbs);
   637         if (!cma_dev->pd) {
   638                 ret = ERR(ENOMEM);
   639                 goto out;
   640         }


And please add Fixes line.

Thanks
