Subject: [PATCH] ALSA: hda/realtek - Fix the mute LED regresion on Lenovo X1 Carbon
Git-commit: 6ba189c5c1a4bda70dc1e4826c58b0246068bb8d
Patch-mainline: v4.20-rc7
References: bsc#1051510

Users reported a mute LED regression on Lenovo X1 Carbon, the root
cause is we applied the fixup of ALC285_FIXUP_LENOVO_HEADPHONE_NOISE
to this machine, then the machine can't apply the fixup of
ALC269_FIXUP_THINKPAD_ACPI anymore. To fix it, we chain two fixup
together.
