I've been working on other stuff and haven't had time to respin this series.

Just to confirm, is the failure due to pinctrl conflicts when the trackpad
variants probe asynchronously?

IIRC either the driver or the DT had comments saying "these zones don't
need trip points". In that case maybe the driver should use
