Re: [PATCH v8 0/7] MR10604: setupapi, ntoskrnl: Implement CM_Get_Parent with device tree properties

[Elizabeth Figura (＠zfigura)]

One thing (I did mention this, but no worries): can we add tests for 1/7, 3/7, and 4/7?

2/7:

```
+    {
+        WCHAR parent_id[MAX_DEVICE_ID_LEN];
+        if (!get_device_instance_id( parent_device, parent_id ))
+            SetupDiSetDevicePropertyW( set, &sp_device, &DEVPKEY_Device_Parent, DEVPROP_TYPE_STRING,
+                    (BYTE *)parent_id, (wcslen( parent_id ) + 1) * sizeof(WCHAR), 0 );
+    }
```

We don't need a scope for this, just put parent_id[] at the beginning. Same for 3/7.

7/7:

```
+    ok(buffer_w[0] != 0, "got empty parent ID\n");
+    trace("DEVPKEY_Device_Parent: %s\n", debugstr_w(buffer_w));
```

Can't we test the actual contents?
