Subject: dm: pci: Pass only device/function to pci_bus_find_devfn()
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=8326f136da6dc496648b8aa75d9717e2e31adad0;p=u-boot.git

dm: pci: Pass only device/function to pci_bus_find_devfn()

In dm_pci_hose_probe_bus(), pci_bus_find_devfn() is called with a bdf
which includes a bus number, but it really should not as this routine
only expects a device/function encoding.
