Initializing the dev pointer inside the\n\"eventdev\" struct in the device probe function fixes this by ensuring we\nhave a valid pointer to return in info_get calls.\n\nFixes: 46a186b1f0c5 (\"event/dsw: add device registration and build system\")\nCc: mattias.ronnblom@ericsson.com\n\nSigned-off-by: Bruce Richardson <bruce.richardson@intel.com>\n---\n drivers/event/dsw/dsw_evdev.c | 1 +\n 1 file changed, 1 insertion(+)", "diff": "diff --git a/drivers/event/dsw/dsw_evdev.c b/drivers/event/dsw/dsw_evdev.c\nindex 785c12f61f..44da3c60d1 100644\n--- a/drivers/event/dsw/dsw_evdev.c\n+++ b/drivers/event/dsw/dsw_evdev.c\n@@ -440,6 +440,7 @@ dsw_probe(struct rte_vdev_device *vdev)\n \t\treturn -EFAULT;\n \n \tdev->dev_ops = &dsw_evdev_ops;\n+\tdev->dev = &vdev->device;\n \tdev->enqueue = dsw_event_enqueue;\n \tdev->enqueue_burst = dsw_event_enqueue_burst;\n \tdev->enqueue_new_burst = dsw_event_enqueue_new_burst;\n", "prefixes": [] }
