Hi,
I have an exception in __pci_bus_size_bridges() when pci_is_root_bus
returns false but bus->self == NULL. My driver registers a virtual bus,
like virtfn_add_bus(). pci_add_new_bus() is called with a parent but
without a pci_dev. Thus bus->parent is set but bus->self is NULL. When
__pci_bus_size_bridges() is called I get an exception at:
switch (bus->self->class >> 8)
The previous version of the code, checking for bus->self != NULL worked
for me. I think an additional check is required to make sure we're not
accessing a NULL pointer.
Best regards
David Engraf
