omap_device prints

I spotted this while booting the OMAP4430 SDP:

omap_device: omap4-keypad.-1: new worst case activate latency 0: 61035

and found that it came from here:

        pr_debug("omap_device: %s: activating\n", od->pdev.name);

                pr_debug("omap_device: %s: pm_lat %d: activate: elapsed time "
                         "%llu nsec\n", od->pdev.name, od->pm_lat_level,
                         act_lat);

                                pr_warning("omap_device: %s.%d: new worst case "
                                           "activate latency %d: %llu\n",
                                           od->pdev.name, od->pdev.id,
                                           od->pm_lat_level, act_lat);
                                pr_warning("omap_device: %s.%d: activate "
                                           "latency %d higher than exptected. "
                                           "(%llu > %d)\n",
                                           od->pdev.name, od->pdev.id,
                                           od->pm_lat_level, act_lat,
                                           odpl->activate_lat);

Is there something wrong with dev_name(&od->pdev.dev) so that we have
consistent naming of devices, rather than poking about inside the
platform_device accessing the name initializers directly ?
