| Subject: ALSA: hda - Turn CX8200 into D3 as well upon reboot |
| |
| From: Park Ju Hyung <qkrwngud825@gmail.com> |
| |
| commit d77a4b4a5b0b2ebcbc9840995d91311ef28302ab upstream. |
| |
| 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. |
