** Description changed:
- I'm on Lenovo ThinkPad X1 Carbon 6th, model 20KH006JGE. After upgrading
- to Linux 4.19.7, the audio mute and microphone mute LEDs (on F1 and F4
- keys) stopped working. They do work if I remove the line:
- {0x12, 0x90a60130},
+ [Impact]
+ The mute led can't work on several lenovo laptop models after applying the
+ patch of #1805079, this is a regression introduced by that patch.
+
+ [Fix]
+ chanin the ALC269_FIXUP_THINKPAD_ACPI, this will make the led work again.
+
+
+ [Test Case]
+ press F1 and F4, the mute led and micmute led work well.
+
+
+ [Regression Potential]
+ Very low, this patch is specific to ALC285_FIXUP_LENOVO_HEADPHONE_NOISE, and
+ this FIXUP is specific several lenovo laptop models. I have tested audio and
+ led functions on those machines.
