12   This function should be used by drivers implementing various input
13   devices to report input events. See also <code class="function">input_inject_event</code>.
14</p></div><div class="refsect1"><a name="idp1114289396"></a><h2>NOTE</h2><p>
15   <code class="function">input_event</code> may be safely used right after input device was
16   allocated with <code class="function">input_allocate_device</code>, even before it is registered
17   with <code class="function">input_register_device</code>, but the event will not reach any of the
18   input handlers. Such early invocation of <code class="function">input_event</code> may be used
19   to 'seed' initial state of a switch or initial position of absolute
20   axis, etc.
