From: Linus Lüssing <linus.luessing@xxxxxx>
This patches fixes two rounding issues in vis.c for sending and
purging vis packets. Before, the timers and timeouts always got
rounded down to seconds, though we want a precision in
milliseconds.
This also fixes a kernel panic that occures when lowering the
timer for sending vis packets (vis_interval) to less than 1000ms
in main.c manually.
