From 6c5705fec63d83eeb165fe61e34adc92ecc2ce75 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 23 Feb 2012 20:19:03 -0700 Subject: powerpc/PCI: get rid of device resource fixups Tell the PCI core about host bridge address translation so it can take care of bus-to-resource conversion for us.

This fixes a build failure ("cast from pointer to integer of different size" in configs where resource_size_t is 64 bits but pointers are 32 bits) I introduced in 6c5705fec63d.
