From: Hui Wang <hui.wang@canonical.com>

commit 6ba189c5c1a4bda70dc1e4826c58b0246068bb8d upstream.

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.
