From: Wei Yang Date: Thu, 3 Mar 2016 23:53:05 +0000 (+1100) Subject: powerpc/pci: Remove VFs prior to PF X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=971427f5827d5a013965878e196d6930a977e8a7;p=linux-beck.git powerpc/pci: Remove VFs prior to PF As commit ac205b7bb72f ("PCI: make sriov work with hotplug remove") indicates, VFs which is on the same PCI bus as their PF, should be removed before the PF. Otherwise, we might run into kernel crash at PCI unplugging time. This applies the above pattern to powerpc PCI hotplug path.
