The platform driver conversion of EINJ mistakenly used platform_device_del() to unwind platform_device_register_full() at module exit. This leads to a small leak of one 'struct platform_device' instance per module load/unload cycle. Switch to platform_device_unregister() which performs both device_del() and final put_device().
