When you hit the half-way mark of the highres # multiplier, small highres movements will incorrectly translate into big # traditional wheel movements, causing odd jitters. # # Simplify the code and make the output stable. # # NOTE! I'm pretty sure this will need further tweaking. But this at # least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into # a usable one. # # Cc: Jiri Kosina # Cc: Harry Cutts # Cc: Benjamin Tissoires # Cc: Peter Hutterer # Signed-off-by: Linus Torvalds #
