From d33047fd7e7d93662622888681861ba84d43c506 Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Mon, 27 Apr 2015 12:33:51 +1000 Subject: powerpc/powernv: Fix early pci_controller_ops loading. Load the PowerNV platform pci controller ops into pci controllers after all the operations are loaded into the platform ops struct, not before. Otherwise we aren't actually setting the ops properly which can break IO for some devices.
