From 817a268516f3aaf9e54c5a0f880de37d03ef4c79 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 14 Sep 2012 17:48:41 -0700 Subject: [PATCH] PCI: Use correct type when freeing bus resource list Should use struct pci_bus_resource instead of struct pci_host_bridge_window Commit 45ca9e9730 ("PCI: add helpers for building PCI bus resource lists") added pci_free_resource_list() and used it in pci_bus_remove_resources(). Later it was also used for host bridge aperture lists, which was fine until commit 0efd5aab41 ("PCI: add struct pci_host_bridge_window with CPU/bus address offset"). That commit added offset information, so we needed a struct pci_host_bridge_window that was separate from struct pci_bus_resource. Commit 0efd5aab41 should have split the host bridge aperture users of pci_free_resource_list() from the pci_bus_resource user (pci_bus_remove_resources()), but it did not.
