The platform device is created at: of_platform_default_populate_init: arch_initcall_sync ->of_platform_populate ->of_platform_device_create_pdata When entering our probe, all the devices should be already created. if it is null, means NODEV. Currently we don't get the fail case. It's a minor fix, no need add fixes tags.
