If anyone has any objections, please let me know. ------------------ From: Johan Hovold 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.
