This patch converts the resource management in PCI fm801 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. Also the superfluous ac97 private_free callbacks were dropped, too.
This should give no user-visible functional changes.
