      NFC: nfcmrvl_uart: fix OF child-node lookup · 737d47bd
      Johan Hovold authored
      [ Upstream commit 5bf59773aaf36dd62117dc83d50e1bbf9ef432da ]
      
      Use the new of_get_compatible_child() helper to lookup the nfc child
      node instead of using of_find_compatible_node(), which searches the
      entire tree from a given start node and thus can return an unrelated
      (i.e. non-child) 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 node).
