commit bcf3588d8ed3517e6ffaf083f034812aee9dc8e2 upstream.
Commit af503716ac14 made sure OF devices get an OF style modalias with I2C events. It assumed all in-tree users were converted, yet it missed some Macintosh drivers.
Add an OF module device table for all windfarm drivers to make them automatically load again.
