From: Michal Privoznik <mprivozn@xxxxxxxxxx>
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.
