commit 47f4469970d8861bc06d2d4d45ac8200ff07c693 upstream.
While commit d5dcce0c414f ("device property: Keep secondary firmware node secondary by type") describes everything correct in its commit message, the change it made does the opposite and original commit c15e1bdda436 ("device property: Fix the secondary firmware node handling in set_primary_fwnode()") was fully correct.
Revert the former one here and improve documentation in the next patch.
