Hi Huang Ying,
I see you are the author of this patch, commit id is:
967577b062417b4e4b8e27b711220f4124f5153a
I have a question while I try to understand this patch,
So I would very grateful if you or others can give me some reply.....
............
- rc = ddi->drv->probe(ddi->dev, ddi->id);
+ pm_runtime_get_sync(dev);
+ pci_dev->driver = pci_drv;
^^^^^^^^^^^^^^^^^^^^^^^^^^
I see here you make the driver to initialize before probe,
But I have no idea of why you do this change.....
and I look inside the code, it may be pm_runtime relate??
Thanks
Mike
