I suggest to improve implementation details another bit at a few source code places.
Examples:
…
> +++ b/drivers/mtd/mtd_virt_concat.c
> @@ -0,0 +1,254 @@
…
> +static int mtd_virt_concat_create_item(struct device_node *parts,
> + unsigned int count)
> +{
+ struct mtd_virt_concat_node *item __free(kfree) = kzalloc(sizeof(*item), GFP_KERNEL);
…
> +int mtd_virt_concat_node_create(void)
> +{
…
+e_nomem:
+ ret = -ENOMEM;
+put_parts:
+ of_node_put(parts);
> +destroy_items:
> + mtd_virt_concat_destroy_items();
> +
> + return ret;
> +}
…
