| Subject: ALSA: hda - fix the micmute led status for Lenovo ThinkCentre AIO |
| |
| From: Hui Wang <hui.wang@canonical.com> |
| |
| commit 386a6539992b82fe9ac4f9dc3f548956fd894d8c upstream. |
| |
| After installing the Ubuntu Linux, the micmute led status is not |
| correct. Users expect that the led is on if the capture is disabled, |
| but with the current kernel, the led is off with the capture disabled. |
| |
| We tried the old linux kernel like linux-4.15, there is no this issue. |
| It looks like we introduced this issue when switching to the led_cdev. |
