[Drbd-dev] Bug in drbd_adm_attach()

[Jan Kara]

  Hello,

  Coverity has spotted a problem in drbd_adm_attach() which does:

        connection = peer_device ? peer_device->connection : NULL;
        conn_reconfig_start(connection);

and conn_reconfig_start() just blindly dereferences 'connection'. So either
peer_device cannot be NULL (and then the test is superfluous) or there's a
bug...
