From 8715aafc5f2f0ea037c0668e3a38bcbd54960437 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 27 Jun 2008 16:57:08 -0600 Subject: [PATCH] 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.
