Use the new of_get_compatible_child() helper to lookup the usb sibling node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related phy-node reference leak. Fixes: f5e4edb8 ("power: twl4030_charger: find associated phy by more reliable means.")
