This patch converts the resource management in PCI cs46xx 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. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-31-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
