Subject: snd_cs46xx regression, producing Oops
Date: Tue, 5 Jul 2022 12:56:14 +0200 (CEST) [thread overview]
Message-ID: <p2p1s96o-746-74p4-s95-61qo1p7782pn@vanv.qr> (raw)
Commit v5.14-rc1-39-g5bff69b3645d introduced a breakage into
snd_cs46xx. When loading the module, an Oops is thrown. The system
works fine afterwards, but the final reboot/poweroff message to ACPI
has no effect after such Oops occurred. (Blacklisting snd_cs46xx
works around the reboot problem.)

ALSA: cs46xx: Allocate resources with device-managed APIs
This patch converts the resource management in PCI cs46xx 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.
