X-Git-Tag: firefly_0821_release~176^2~5787^2~2^2~2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d35329d9f17f05277f2718eb54402dea3e833d19;p=firefly-linux-kernel-4.4.55.git

PCI: Drop redundant setting of bus->is_added in virtfn_add_bus()

The flag pci_bus->is_added is used to guard invocation of
pcibios_fixup_bus(pci_bus).  When virtfn_add_bus() is called, the
pci_bus->is_added flag has already been set, so remove the redundant

	bus->is_added = 1;
