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.
changes in v2:
- commit message enhanced
- removed hid-quirk.c hunk
- merged separate patches into one single patch
