The recent cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free(). This patch fixes it by calling snd_card_free() on the error from the probe callback using a new helper function.
