Seems to be a common theme:
google> grep --color=never "platform.*register" *.c
coreboot_table-acpi.c: return
platform_driver_register(&coreboot_table_acpi_driver);
coreboot_table-of.c: return
platform_driver_register(&coreboot_table_of_driver);
gsmi.c: gsmi_dev.pdev = platform_device_register_full(&gsmi_dev_info);
gsmi.c: platform_device_unregister(gsmi_dev.pdev);
gsmi.c: platform_device_unregister(gsmi_dev.pdev);
[looks good]
memconsole-coreboot.c: pdev = platform_device_register_simple("memconsole",
-1, NULL, 0);
memconsole-coreboot.c: platform_driver_register(&memconsole_driver);
vpd.c: pdev = platform_device_register_simple("vpd", -1, NULL, 0);
vpd.c: platform_driver_register(&vpd_driver);
