[PATCH libevdev 4/4] Support EV_REP values through libevdev_get_event_value

[Peter Hutterer]

We shouldn't have a separate API for that, the whole point of libevdev is to
abstract the quirkyness of the ioctls into a common interface. So let's
export the two EV_REP values through libevdev_get_event_value.
