Subject: Input: twl6040-vibra - fix child-node lookup

From: Johan Hovold <[email protected]>

commit dcaf12a8b0bbdbfcfa2be8dff2c4948d9844b4ad upstream.

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children.

Later sanity checks on node properties (which would likely be missing) should prevent this from causing much trouble however, especially as the original premature free of the parent node has already been fixed separately (but that "fix" was apparently never backported to stable).
