input_id: Identify scroll-wheel device on Trust TB7300 tablet as keyboard
The Trust TB7300 (relabelled Waltop?) tablet has a scrollwheel which shows up as a /dev/input/event# node all by itself. Currently input_id does not set any ID_INPUT_FOO attr on this causing it it to not be recognized by Xorg / libinput. This commit fixes this by marking it with ID_INPUT_KEY. Reported-by: Sjoerd Timmer <themba@randomdata.nl>
