[Sean Rhodes]

Support the new StarFighter HDA SSID while keeping the existing SSID chained to the same quirk until the new match reaches backports.

Applied both patches to for-next branch now.  Thanks.

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?

A good point. If you come up with a new change, try to make a patch on
top of the latest sound git tree for-next branch.
