of: use of_get_child_by_name() to find child node
...
After iterating the children of a node with for_each_child_of_node(),
the child node will never be NULL. If the node was not found,
overlay_child will always point to the first element in the list, which
might or might not be the node that was searched.
Use the of_get_child_by_name() helper function to find the child node
with the name, which does the right thing and returns NULL if the node
is not found.
