Investigation showed the device ID 0xA0D0 was missing from the kernel's pci_device_id table, even though it was added to mainline Linux 6.14 in March 2025.

That device ID has never been added to linux upstream.  It is only found
in the linux-surface patches which do not appear to have been submitted
for inclusion at this time.

I see it here:
