As of_platform_populate _always_ return 0 no matter what, the only way to reach that message is if probing the child failed. As I cannot see into the future when of_platform_populate might actually be changed to return meaningful codes, we shouldn't try to foresee what the actual problem might be today either. This is a battle for another day.
