+Subject: [PATCH 4/9] Add IdeaPad WMI Fn Keys driver
+
+Create an input device for WMI events corresponding to some special
+keys on the 'Lenovo Yoga' line.
+
+This include the 3 keys to the right on the 'Lenovo Yoga9 14IAP7' and
+additionally the 'Lenovo Support' and 'Lenovo Favorites' (star with 'S'
+inside) in the fn key row.
