pci: don't overwrite multi functio bit in pci header type.
Don't overwrite pci header type. Otherwise, multi function bit which pci_init_header_type() sets appropriately is lost. Anyway PCI_HEADER_TYPE_NORMAL is zero, so it is unnecessary to zero which is already zero cleared. how to test: run qemu and issue info pci to see whether a device in question is normal device, not pci-to-pci bridge. This is handy because guest os isn't required. tested changes: The following files are covered by using following commands. sparc64-softmmu apb_pci.c, vga-pci.c, cmd646.c, ne2k_pci.c, sun4u.c ppc-softmmu grackle_pci.c, cmd646.c, ne2k_pci.c, vga-pci.c, macio.c ppc-softmmu -M mac99 unin_pci.c(uni-north, uni-north-agp) ppc64-softmmu pci-ohci, ne2k_pci, vga-pci, unin_pci.c(u3-agp) x86_64-softmmu acpi_piix4.c, ide/piix.c, piix_pci.c -vga vmware vmware_vga.c -watchdog i6300esb wdt_i6300esb.c -usb usb-uhci.c -sound ac97 ac97.c -nic model=rtl8139 rtl8139.c -nic model=pcnet pcnet.c -balloon virtio virtio-pci.c: untested changes: The following changes aren't tested. prep_pci.c: ppc-softmmu -M prep should cover, but core dumped. unin_pci.c(uni-north-pci): the caller is commented out. openpic.c: the caller is commented out in ppc_prep.c Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
