From: Johan Hovold johan@kernel.org

commit bc6476d6c1edcb9b97621b5131bd169aa81f27db 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.

To make things worse, the parent codec node was also prematurely freed.
