Subject: Input: twl4030-vibra - fix sibling-node lookup
From: Johan Hovold <johan@xxxxxxxxxx>
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.
Fixes: 64b9e4d803b1 ("input: twl4030-vibra: Support for DT booted kernel")
Fixes: e661d0a04462 ("Input: twl4030-vibra - fix ERROR: Bad of_node_put() warning")
