From 38ae9ec40f06f3aef5c25314f432113cf2c1340a Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Tue, 31 Mar 2015 16:00:50 +1100 Subject: [PATCH] powerpc/pseries: Move controller ops from ppc_md to controller_ops This moves the pSeries platform to use the pci_controller_ops structure, rather than ppc_md for PCI controller operations.
