Re: [PATCH v2] ALSA: hda: handle UAF at probe error

Call snd_card_free_on_error() on probe error instead of calling snd_card_free() which should handle devres call orders.

This won't change any practical behavior, because HD-audio driver doesn't use snd_devm_card_new(). snd_card_free() still gets called explicitly in the relevant code paths.

Issues: https://gitlab.freedesktop.org/drm/intel/-/issues/5701

So it must be a different cause for this problem...
