[patch 08/15] PNP: in debug resource dump, make empty list obvious
|
|
If the resource list is empty, say that explicitly. Previously,
it was confusing because often the heading was followed by zero
resource lines, then some "add resource" lines from auto-assignment,
so the "add" lines looked like current resources.
