[PATCH v2 0/2] of: fdt: fix memory leak and oob writes in fdt_ensure_space

[Stefan Kerkmann]

I have encountered the oob write while attempting to modify a large FIT
image with of_property. While hunting for the root cause I noticed that
there is a potential memory leak in fdt_ensure_space as well. Both is
fixed in this series.
