+Subject: [PATCH] HID: rmi: Disable populating F30 when the touchpad has
+ physical buttons
+
+Physical buttons do not use F30 to report their state and in some cases the
+data reported in F30 is incorrect and inconsistent with what is reported by
+the HID descriptor. When physical buttons are present, ignore F30 and let
+hid-input report buttons based on what is defined in the HID descriptor.
