Re: [Linux-stable-mirror] [PATCH 1/2] mfd: twl4030-audio: fix sibling-node lookup

A helper purported to look up a child node based on its name was using the wrong of-helper and ended up prematurely freeing the parent of-node while leaking any matching node.

To make things worse, any matching node would not even necessarily be a child node as the whole device tree was searched depth-first starting at the parent.
