Since kernel commit 928bea964827 ("PCI: Delay enabling bridges until they're needed"), pci fixups are run with bridges (e.g. the pcie port) disabled. This causses hangs when ath9k_pci_fixup tries to manually enable the device to apply the register fixups. Fix this by enabling any parent bridges before trying to access the device itself. Fixes boot on DSL-274XB rev F1. Reported-by: Matteo Croce <matteo@openwrt.org> Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 41856master
