Sorry,

if the ->probe() failed, then the ->remove() will *NOT* get called.


I'm doing the test by add a line before the drm_dev_alloc()

I do the test by adding one line code before the drm_dev_alloc() function

 to generate a fault(error) manually,



See below:

```

    return -ENODEV;

    dev = drm_dev_alloc(&kms_driver, &pdev->dev);
    if (IS_ERR(dev))
        return PTR_ERR(dev);

    ret = pci_enable_device(pdev);
    if (ret)
        goto err_free;
```


So, there is no problem, as far as I can see.
All in all,  if the ->probe() failed, then the ->remove() will *NOT* get called.
