The function platform_set_drvdata copies the value the variable card to card->dev->driver_data, then the address of &pdev->dev is assigned to card->dev in atmel_classd_asoc_card_init, but when calling snd_soc_register_card,the function dev_set_drvdata(card->dev, card) will do the same copy operation, so i think that the former copy operation can be removed.
