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).

I also tested your twl4030-vibra patch on GTA04.

No regressions observed.

Thanks for testing.
