Subject: [PATCH 4.16 096/279] HID: lenovo: Add support for IBM/Lenovo Scrollpoint mice
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: pgzh <peter.ganzhorn@...il.com>
[ Upstream commit a230cd52b8a2be39cd6e9a13b3e62af57f21372a ]
The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a
scrolling wheel capable of 2-D (vertical+horizontal) scrolling. hid-generic
does only expose 1-D (vertical) scrolling functionality for these mice. This
patch adds support for horizontal scrolling for the IBM/Lenovo Scrollpoint mice
to hid-lenovo.
[jkosina@...e.cz: remove change versioning from git changelog]
