I'm not sure if this is 4.0 material, it does fix a real regression, the fix is pretty simple and safe (*), and when triggered the behavior (stuck mouse button) is nasty, which all counts in favor of fixing this. OTOH this only affects somewhat older hardware and only a certain usage pattern (using the trackpoint with the touchpad buttons). Anyways the call if this is 4.0 material is up to you (Linus and Dmitry), I'm just trying to make sure you're aware of this issue and the patch. The details of the actual bug + fix can be found in the commit msg of the patch. Regards, Hans *) The fix restores 3.19 behavior for alps v2 dualpoint touchpad/stick combos
