Subject: powerpc/powernv/pci: use pci_dev_id() to simplify the code
X-Git-Tag: v6.6.17~4052^2~86
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe8aa8e3379326ecb77203cae50e8e83c054aedc;p=platform%2Fkernel%2Flinux-rpi.git

powerpc/powernv/pci: use pci_dev_id() to simplify the code

PCI core API pci_dev_id() can be used to get the BDF number for a pci
device. We don't need to compose it mannually. Use pci_dev_id() to
simplify the code a little bit.
