From e031577eef6118bd9c4f3ec319f69986531cd32c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 15 Jul 2021 09:59:17 +0200 Subject: ALSA: ad1848: Allocate resources with device-managed APIs This patch converts the resource management in ISA ad1848 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper. The remove callback became superfluous and dropped. This should give no user-visible functional changes.
