Your patch is white space damaged and doesn't apply.  Read the first

Just put this kind of comments under the --- cut off line.  We're used
to reviewing patches like this so it's not a big deal.

nvmem_add_cells_from_dt() is cleaning up from:
	addr = of_get_property(child, "reg", &len);
so that's why it does:
	of_node_put(child);

It's not necessary in u_boot_env_add_cells().
