PCI: Fix device class print out
Found debug print of class is shifted. | pci 0000:f8:15.2: [8086:2b56] type 0 class 0x000600 Code is trying to print class with 6 digits, but use shifted class with 4 digits valid value as variable. Change to original dev->class directly. Also remove not needed calculating of local variable class, because it will be updated after pci_fixup_device(pci_fixup_early...) Also unify type print out when class and header is not matched. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
