[PATCH 45/51] ALSA: vx222: Allocate resources with device-managed APIs

Tue Jul 13 16:28:51 CEST 2021
This patch converts the resource management in PCI vx222 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.
