From 596ae97ab0ce0ac273162d51424d7a509b557f32 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 15 Jul 2021 09:59:05 +0200 Subject: [PATCH] ALSA: oxygen: Allocate resources with device-managed APIs 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.
