OF: fix of_find_node_by_path() assumption that of_allnodes is root
of_find_node_by_path() is borked because of_allnodes is not guaranteed to contain the root of the tree after using any of the dynamic update functions because some other nodes ends up as of_allnodes. Fixes: c22e650e66b8 of: Make of_find_node_by_path() handle /aliases Reported-by: pantelis.antoniou@konsulko.com Signed-off-by: Frank Rowand <frank.rowand@sonymobile.com> Signed-off-by: Rob Herring <robh@kernel.org>
