of: fdt: add missing allocation-failure check
The memory allocator passed to __unflatten_device_tree() (e.g. a wrapped kzalloc) can fail so add the missing sanity check to avoid dereferencing a NULL pointer. Fixes: fe14042358fa ("of/flattree: Refactor unflatten_device_tree and add fdt_unflatten_tree") Cc: stable <stable@vger.kernel.org> # 2.6.38 Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Rob Herring <robh@kernel.org>
