Subject: [PATCH v2] Input: set INPUT_PROP_POINTING_STICK in hid-lenovo
Date: Wed, 08 Apr 2015 11:36:07 +0200	[thread overview]
Message-ID: <1428485767.14997.1@smtp.gmail.com> (raw)

Set flags INPUT_PROP_POINTER and INPUT_PROP_POINTING_STICK for the
trackpoint integrated in Lenovo USB and Bluetooth keyboards. Libinput 
checks
these flags to enable features such as middle-button-scrolling by 
default.
