From 44b372d8a099a7042f9f17ebd4941050e38c1773 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 24 Jun 2012 18:24:44 +0000 Subject: [PATCH] powerpc/vio: Separate vio bus probe and device probe Similar to PCI, separate the bus probe from device probe. This allows us to attach bus notifiers for DMA debug and IOMMU fault injection before devices have been probed.
