commit c01b723a56ce18ae66ff18c5803942badc15fbcd upstream.
The previous 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.
