Or maybe this should be

+               if ((ctrl->subsys->cmic & NVME_CTRL_CMIC_MULTI_CTRL) && info->is_shared) {
+                       dev_warn(ctrl->device,
+                               "Found shared namespace %d but multipathing not supported.\n",
+                               info->nsid);
