+Subject: [PATCH libinput] touchpad: fix stuck finger after a click
+
+On a touchpad without resolution, the pinned finger was stuck. The motion
+distance scale factor ended up as 0 and the finger never reached the threshold
+of 3mm.
+int was not the best choice of datatype for a value of 0.007...
+
+Fix the data types for xdist/ydist at the same time, clamping to int may cause
+erroneous (un)pinning.
+
+Introduced in 8025b374d564f4a30b089e5cf6fd65e0c6af8da2
