From d81a84e7bba0a42b6205f7a4a592f4214c86bb48 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Mon, 10 Aug 2020 10:16:59 +0800 Subject: [PATCH] ALSA: hda - fix the micmute led status for Lenovo ThinkCentre AIO 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.
