[PATCH evdev 3/3] Use libevdev as backend
Peter Hutterer
peter.hutterer at who-t.net
Thu Oct 3 23:19:57 PDT 2013
Removes the need to ioctl manually and check bits, with all the dangers that
come with that. libevdev is much better prepared for invalid values, OOB
checks, etc.
Plus, we get almost free SYN_DROPPED handling as well which we didn't have
before.
