From 819beac3806a5e986d81f476b999b7fffce1a233 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.
