OK.

I changed track@3 to track@30, and track@4 to track@40.
Then I added the reg property to .../ride@.../track@30/ and
.../ride@.../track@40/ in the base dts since those nodes
exist in the base dts.  As a result, W=2 will still warn
about a missing reg property for these two nodes in
the overlay.

OK.
