4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan@kernel.org
commit 964728f9f407eca0b417fdf8e784b7a76979490c upstream.
Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children.
Note that the original premature free of the parent node has already been fixed separately, but that fix was apparently never backported to stable.
