Ah, I see. It was commented out by the branch work/letux-base/dt-gta04a5
which is no longer merged. So it looks that our dt-upstream branch is incomplete
and missing some parts.

It will be easier to compare as soon as the 30 gta04 patches arrive upstream
and the dt-upstream is shortened and the branches it replaces have to be
rebased. Ideally they would become empty... Or they show some remaining diffs.

BR and thanks for finding!

I have added a patch that just comments out the jack-det-gpio. Maybe someone
we find someone who looks why it fails. At the moment it seems to be more
important to have any sound than (better) headset detection working.
