8   This sets the inactivity timeout for a particular device on a
9   port.  This affects functions like <code class="function"><a class="link" href="API-parport-wait-peripheral.html" title="parport_wait_peripheral">parport_wait_peripheral</a></code>.
10   The special value 0 means not to call <code class="function">schedule</code> while dealing
11   with this device.
12   </p><p>
13
14   The return value is the previous inactivity timeout.
15   </p><p>
16
17   Any callers of <code class="function"><a class="link" href="API-parport-wait-event.html" title="parport_wait_event">parport_wait_event</a></code> for this device are woken
18   up.
