+Subject: [PATCH] macintosh: windfarm: fix MODINFO regression
+
+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.
+
+Fixes: af503716ac14 ("i2c: core: report OF style module alias for devices registered via OF")
