[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

Hello Moti Haimovski,

The patch 2a0a839b6a28: "habanalabs: extend fatal messages to contain
PCI info" from Dec 29, 2022, leads to the following Smatch static
checker warning:

	drivers/accel/habanalabs/common/device.c:2336 hl_device_init()
	warn: address of NULL pointer 'hdev->pdev'

drivers/accel/habanalabs/common/device.c
    2322 early_fini:
    2323         device_early_fini(hdev);
    2324 free_dev:
    2325         put_device(hdev->dev_ctrl);
    2326         put_device(hdev->dev);
    2327 out_disabled:
    2328         hdev->disabled = true;
    2329         if (expose_interfaces_on_err)
    2330                 cdev_sysfs_debugfs_add(hdev);
    2331         if (hdev->pdev)
                     ^^^^^^^^^^
NULL check.

    2332                 dev_err(&hdev->pdev->dev,
    2333                         "Failed to initialize hl%d. Device %s is NOT usable !\n",
    2334                         hdev->cdev_idx, dev_name(&(hdev)->pdev->dev));
    2335         else
--> 2336                 pr_err("Failed to initialize hl%d. Device %s is NOT usable !\n",
    2337                         hdev->cdev_idx, dev_name(&(hdev)->pdev->dev));
                                                          ^^^^^^^^^^^^^^^^^^
"hdev->pdev" is NULL here so this will crash.

    2338 
    2339         return rc;
    2340 }
