of: return NUMA_NO_NODE from fallback of_node_to_nid()
commit c8fff7bc5bba6bd59cad40441c189c4efe7190f6 upstream. Node 0 might be offline as well as any other numa node, in this case kernel cannot handle memory allocation and crashes. Signed-off-by: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Fixes: 0c3f061c195c ("of: implement of_node_to_nid as a weak function") Signed-off-by: Grant Likely <grant.likely@linaro.org> Signed-off-by: Luis Henriques <luis.henriques@canonical.com>
