The "else branch" in "#if IS_ENABLED(CONFIG_NET_DEVLINK)" is the
problem:

static inline int
devlink_resource_register(struct devlink *devlink,
                          const char *resource_name,
                          bool top_hierarchy,
                          u64 resource_size,
                          u64 resource_id,
                          u64 parent_resource_id,
                          const struct devlink_resource_size_params *size_params,
                          const struct devlink_resource_ops *resource_ops)
{
        return 0;
}
