Re: [PATCH v5 0/5] MR7727: cfgmgr32, setupapi: Implement a few functions.

[Elizabeth Figura (＠zfigura)]

From 1/5:

```
+    if (!(instance_id = malloc((len - 4 + 1) * sizeof(*instance_id))))
+    {
+        SetLastError(ERROR_NOT_ENOUGH_MEMORY);
+        goto done;
+    }
```

That's not going to do the right thing anymore; the "done" label now overwrites the last error (I'm not quite sure why, since it should only need to be set in one case).

```
+            ret = TRUE;
+            break;
```

Bikeshedding, but that's exactly as many lines as "free(instance_id); return TRUE;"...
