commit de9a01bc95a9e5e36d0659521bb04579053d8566 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.
