Where? Nothing sets id to NULL in nvme_identify_n(), what am I missing?

Where? I think you may be looking at a different code base?

int nvme_identify_ns(struct nvme_ctrl *ctrl, unsigned nsid,
                         struct nvme_id_ns **id)
{
         ....
         error = nvme_submit_sync_cmd(ctrl->admin_q, &c, *id, sizeof(**id));
         if (error) {
                 dev_warn(ctrl->device, "Identify namespace failed 
(%d)\n", error);
                 kfree(*id);
         }
         return error;
}

I don't see how this patch makes sense...
