[PATCH 07/10] of: Make sure attached nodes don't carry along extra children

[Grant Likely]

The child pointer does not get cleared when attaching new nodes which
could cause the tree to be inconsistent. Clear the child pointer in
__of_attach_node() to be absolutely sure that the structure remains in a
consistent layout.
