This is usually fine, but in the case of something like a "simple-mfd" node such as "raspberrypi,bcm2835-firmware", those child nodes will not be populated. And subsequent calls won't work either because the /firmware node is marked as processed already. Switch the call to of_platform_default_populate() to solve this problem. It should be a nop for existing cases.
