CWE-416 Use After Free

Description

In the Linux kernel, the following vulnerability has been resolved: ALSA: 6fire: Release resources at card release The current 6fire code tries to release the resources right after the call of usb6fire_chip_abort(). But at this moment, the card object might be still in use (as we&#39;re calling snd_card_free_when_closed()). For avoid potential UAFs, move the release of resources to the card&#39;s private_free instead of the manual call of usb6fire_chip_destroy() at the USB disconnect callback.
