From 9e33002fd1791bcab626b19301670484c1cb6d50 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 19 Jun 2014 17:22:44 +1000 Subject: PCI: Make resetting secondary bus logic common Commit d92a208d086 ("powerpc/pci: Mask linkDown on resetting PCI bus") implemented same logic (resetting PCI secondary bus by bridge's config register PCI_BRIDGE_CTL_BUS_RESET) in PCI core and arch-dependent code. To avoid the duplication, move the logic to pci_reset_secondary_bus(). That commit did not declare the pcibios_reset_secondary_bus() interface in linux/include/pci.h. Add the declaration. No functional change.
