From aa92050f10f0c904df5ae58e3b2c70c9e4ef67c2 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 15 Jul 2021 09:59:36 +0200 Subject: ALSA: mtpav: Allocate resources with device-managed APIs This patch converts the resource management in mtpav driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper now. This should give no user-visible functional changes.
