trackpad keys not working properly on Lenovo Thinkpad T460s

[Lukas Humbel]

When using the trackpad buttons of the Lenovo T460s, the release event will be triggered automatically. This makes it impossible to perform drag and drop operations.

The bug is described and resolved in the kernel bugtracker [1]. The fix they describe works fine on the ubuntu kernel 4.4.0-15-generic. Back-porting this bugfix would make life better for T460s user, thanks for consideration.
