+Commit b6cc0ba2cbf4 (HID: add support for Apple Magic Keyboards)
+backported support for the Magic Keyboard over Bluetooth, but did not
+add the BT_VENDOR_ID_APPLE to hid_have_special_driver[] so the hid-apple
+driver is never loaded and Fn key does not work at all.
+
+Adding BT_VENDOR_ID_APPLE to hid_have_special_driver[] is not needed
+after commit e04a0442d33b (HID: core: remove the absolute need of
+hid_have_special_driver[]), so 4.16 kernels and newer does not need it.
+
+Fixes: b6cc0ba2cbf4 (HID: add support for Apple Magic Keyboards)

+Benjamin, thank you for your help with this.
+
+I believe this is needed for both linux-4.14.y and linux-4.9.y.
