Subject: Input: twl4030-vibra - fix sibling-node lookup

From: Johan Hovold <[email protected]>

commit 5b189201993ab03001a398de731045bfea90c689 upstream.

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 searching the whole device tree depth-first starting at the parent node.
