Re: [libvirt] [PATCH 01/18] virpcimock: Move actions checking one level up

The pci_driver_bind() and pci_driver_unbind() functions are "internal implementation", meaning other parts of the code should be able to call them and get the job done. Checking for actions (PCI_ACTION_BIND and PCI_ACTION_UNBIND) should be done in handlers (pci_driver_handle_bind() and pci_driver_handle_unbind()). Surprisingly, the other two actions (PCI_ACTION_NEW_ID and PCI_ACTION_REMOVE_ID) are checked already at this level.
