From 342d6666f7276723e418b91c885b0c03f02eeaaf Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 6 May 2013 12:03:49 +1000 Subject: [PATCH] powerpc/cell/iommu: Improve error message for missing node Some devices don't have a correct node ID and thus can't be attached to an iommu. The message displayed by the iommu code isn't very useful if you don't have a device-tree node as it tries to print the device-tree path but not the struct device name. Improve this by printing the device name as well.
