Subject: ASoC: twl4030: fix child-node lookup

From: Johan Hovold <[email protected]>

commit 15f8c5f2415bfac73f33a14bcd83422bcbfb5298 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, while the child node was leaked.
