From 8a3d01c740ab5ce141af8ddeef23cecaa51d2710 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 24 Jan 2014 14:51:49 -0700 Subject: [PATCH] x86/PCI: Use NUMA_NO_NODE, not -1, for unknown node NUMA_NO_NODE is the usual value for "we don't know what node this is on," e.g., it is the error return from acpi_get_node(). This changes uses of -1 to NUMA_NO_NODE. NUMA_NO_NODE is #defined to be -1 already, so this is not a functional change. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J.
