Zbigniew Jędrzejewski-Szmek fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

<function>udev_device_get_subsystem()</function>,
<function>udev_device_get_driver()</function> and
<function>udev_device_get_action()</function> return a pointer
to a constant string that describes the requested property. The
lifetime of this string is bound to the device it was requested
on. On failure, each function may return
<constant>NULL</constant>.</para>
<para>On success, <function>udev_device_get_devnum()</function>
returns the device type of the passed device. On failure, a
device type with minor and major number set to
<constant>0</constant> is returned.</para>
<para><function>udev_device_get_udev()</function> always returns
a valid pointer to the udev context that this device belongs
to.</para>
<para>On success, <function>udev_device_get_parent()</function>
and
<function>udev_device_get_parent_with_subsystem_devtype()</function>
return a pointer to the parent device. No additional reference
to this device is acquired, but the child device owns a reference
to such a parent device. On failure, <constant>NULL</constant>
is returned.</para>
<para>On success, <function>udev_device_get_is_initialized()</function> returns either <constant>1</constant> or
<constant>0</constant>, depending on whether the passed device has already been initialized by udev or not. On
failure, a negative error code is returned. Note that devices for which no udev rules are defined are never
reported initialized.</para>
