[PATCH 38/51] ALSA: oxygen: Allocate resources with device-managed APIs
Takashi Iwai

Tue Jul 13 16:28:44 CEST 2021
This patch converts the resource management in PCI oxygen drivers with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the page allocations are
done with the devres helper.
This should give no user-visible functional changes.
