This prepares the device for use by other layers by initializing
its fields.
It is the first half of <code class="function">device_register</code>, if called by
that function, though it can also be called separately, so one
may use <em class="parameter"><code>dev</code></em>'s fields. In particular, <code class="function">get_device</code>/<code class="function">put_device</code>
may be used for reference counting of <em class="parameter"><code>dev</code></em> after calling this
function.
</p></div><div class="refsect1" title="NOTE"><a id="id2619944"></a><h2>NOTE</h2><p>
Use <code class="function">put_device</code> to give up your reference instead of freeing
<em class="parameter"><code>dev</code></em> directly once you have called this function.
