pci_add_new_bus() calls pci_alloc_child_bus() which calls pci_alloc_bus() that allocates memory dynamically with kzalloc(). The return value of kzalloc() is the pointer that's eventually returned from pci_add_new_bus(), so since kzalloc() can fail and return NULL so can pci_add_new_bus(). Thus we may end up dereferencing a NULL pointer in drivers/pci/probe.c::pci_scan_bridge(). Seems to me we should test for this and bail out if it happens rather than crashing. Also removed some trailing whitespace that bugged me while looking at this. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
