Seems like:

Fixes: ffb9fc68dff3 ("x86: dtb: Add device tree support for HPET")

and would be appropriate, right?

Also, how was this found, and what is the impact from not fixing it?
Was it causing horrible problems in production, or was it just something
that was found by inspection that's not causing any real problems in
practice?
