Subject: dbus: add data argument to BusPropertySetCallback
X-Git-Tag: v183~415
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9612f07cbf2b0ec54c5dc6ed7e521e181cc3612d;p=systemd

dbus: add data argument to BusPropertySetCallback

BusPropertyCallback already has the argument. It is necesary for the
callback to know what data to access.
