From d77a4b4a5b0b2ebcbc9840995d91311ef28302ab Mon Sep 17 00:00:00 2001 From: Park Ju Hyung Date: Sat, 28 Jul 2018 03:16:21 +0900 Subject: [PATCH] ALSA: hda - Turn CX8200 into D3 as well upon reboot As an equivalent codec with CX20724, CX8200 is also subject to the reboot bug. Late 2017 and 2018 LG Gram and some HP Spectre laptops are known victims to this issue, causing extremely loud noises upon reboot. Now that we know that this bug is subject to multiple codecs, fix the comment as well.
