From 3099406ef4832124ce572cfbbc914e8a385ca38f Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 23 Jun 2021 16:46:01 +0300 Subject: ALSA: hda: Release codec display power during shutdown/reboot Similarly to the previous patch for the HDA controller make sure here that codecs also drop the display power reference during shutdown and reboot. This fixes a power ref leaked WARN in i915 during shutdown if the HDA driver is built with CONFIG_PM=n.
