Maybe this should be done in dev_coredumpm instead of in the driver?

Could make it a single line:

	drm_info(dev, "Device core dump created in /sys/class/drm/card%d/device/devcoredump/data\n",
		 dev->primary->index);

(AFAICT drm_info prints the driver name twice already, no need for a third time :)
