From 0af83d2e447af3e5098583cb6320bb1b1fb0976b Mon Sep 17 00:00:00 2001 From: Ilya Lipnitskiy Date: Tue, 13 Apr 2021 20:12:39 -0700 Subject: [PATCH] MIPS: pci-legacy: remove busn_resource field No drivers set the busn_resource field in the pci_controller struct. Commit 7ee214b540d9 ("MIPS: PCI: Remove unused busn_offset") almost removed it over 3 years ago. Remove it for good to free up memory and eliminate messages like: pci_bus 0000:00: root bus resource [??? 0x00000000 flags 0x0] Signed-off-by: Ilya Lipnitskiy Cc: Bjorn Helgaas Signed-off-by: Thomas Bogendoerfer --- arch/mips/include/asm/pci.h | 1 - arch/mips/pci/pci-legacy.c | 1 - 2 files changed, 2 deletions(-) diff --git a/arch/mips/include/asm/pci.h b/arch/mips/include/asm/pci.h index 6f48649..9ffc819 100644 --- a/arch/mips/include/asm/pci.h +++ b/arch/mips/include/asm/pci.h @@ -38,7 +38,6 @@ struct pci_controller { struct resource *io_resource; unsigned long io_offset; unsigned long io_map_base; - struct resource *busn_resource; #ifndef CONFIG_PCI_DOMAINS_GENERIC unsigned int index; diff --git a/arch/mips/pci/pci-legacy.c b/arch/mips/pci/pci-legacy.c index ec3f52a..78c2298 100644 --- a/arch/mips/pci/pci-legacy.c +++ b/arch/mips/pci/pci-legacy.c @@ -89,7 +89,6 @@ static void pcibios_scanbus(struct pci_controller *hose) hose->mem_resource, hose->mem_offset); pci_add_resource_offset(&resources, hose->io_resource, hose->io_offset); - pci_add_resource(&resources, hose->busn_resource); list_splice_init(&resources, &bridge->windows); bridge->dev.parent = NULL; bridge->sysdata = hose; -- 2.7.4
