extending setupapi

[Juan Lang]

Hi Pieter, overall your patch looks good, but it has some minor errors
that get in the way:

-    struct DeviceInfo *devInfo = SETUPDI_AllocateDeviceInfo(set, set->cDevices,
-            instanceId, phantom);
+    struct DeviceInfo *devInfo;

     TRACE("%p, %s, %d, %s, %d\n", set, debugstr_guid(guid), devInst,
             debugstr_w(instanceId), phantom);

+    devInfo = SETUPDI_AllocateDeviceInfo(set, set->cDevices,
+            instanceId, phantom);
+
This change is unrelated to the function you're implementing, please
send it in a separate patch if you want this change to go in.

+          debugstr_a(machine), reserved);

Same here..

+    interfacesKey = SetupDiOpenClassRegKeyExW(interface, KEY_READ,
+            DIOCR_INTERFACE, NULL, NULL);
+
and here..

In general we alphabetize function names in spec files, so please
don't change the order.

Thanks for your help with Wine.
