ChangeSet 1.1759, 2004/05/28 13:37:08-07:00, lcapitulino@prefeitura.sp.gov.br [PATCH] PCI: fix pci/probe.c possible NULL pointer. In drivers/pci/probe.c::pci_scan_bridge() the call for pci_alloc_child_bus() can return NULL, but it is not handled by the function (detected by Coverity's checker). The patch bellow fix that returning `max' if we got the NULL, but I do not know if it is right. I guess it is, because in that case the function will act in the same way as with `pass != 0'.
