[PATCH weston v2 5/8] libinput: don't use weston_config when configuring input devices
Giulio Camuffo

Wed Jun 1 18:43:27 UTC 2016
Instead add callbacks to the drm and fbdev backends and pass that to
the input backens so that when a new device needs to be configured
that is called and the compositor can configure it.
