iio: event_monitor: Flush output on event
By flushing the output, iio_event_monitor can be more useful to programs chained along with it. iio_event_monitor stk3310 | awk '/rising/{system("my_unlockscreen.sh")} /falling/{system("my_lockscreen.sh")}' Without this flush, the above example would buffer a number of events, then after a while run the lock/unlock scripts several times.
