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