Thanks for the report and the analysis.

The driver-core prerequisite (cb3d1049f4ea) is already queued for
6.6.y - The companion bdddb54c533f ("driver core: platform: use generic
driver_override infrastructure") is queued too. Once 6.6.142 ships the build
error should resolve.

Newer LTS branches (6.12/6.18/7.0) already have the prerequisite as
an ancestor, so only 6.6.y was affected.
