+Subject: [PATCH] HID: logitech-hidpp: add a module parameter to keep firmware
+ gestures
+
+The Logitech T650 used to report 3 fingers swipes to the up as a press on the
+Super key. When we switched the touchpad to the raw mode, we also disable such
+firmware gesture and some users may rely on it.
+
+Unfortunately, 3 finger swipes are still not supported in most of the Linux
+environments, which means that we disabled a feature of the touchpad.
+
+Allow users to revert the raw reporting mode and keep going with the firmware
+gestures by providing a new module parameter.
