I guess the reason you're creating a new quirk is because the existing
ALC269_FIXUP_LIMIT_INT_MIC_BOOST is chained to ALC269_FIXUP_THINKPAD_ACPI.
This makes the quirk identical to ALC269_FIXUP_THINKPAD_ACPI. Would it be
worth reworking the existing ALC_269_FIXUP_LIMIT_INT_MIC_BOOST to not be
chained and then create a new ALC269_FIXUP_THINKPAD_LIMIT (or similar) for
whichever devices that need it?
