From: "Mike Rapoport (Microsoft)" <rppt@kernel.org> Currently of_numa_parse_memory_nodes() returns 0 if no "memory" node in device tree contains "numa-node-id" property. This makes of_numa_init() to return "success" despite no NUMA nodes were actually parsed and set up. arch_numa workarounds this by returning an error if numa_nodes_parsed is empty. numa_memblks however would WARN() in such case and since it will be used by arch_numa shortly, such warning is not desirable. Make sure of_numa_init() returns -EINVAL when no NUMA node information was found in the device tree. Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> ---
