Subject: ASoC: da7218: fix fix child-node lookup
From: Johan Hovold <johan@xxxxxxxxxx>
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.
