[PATCH] PCI: Remove unused EXPORT_SYMBOL()s from drivers/pci/bus.c

[PATCH] PCI: Remove unused EXPORT_SYMBOL()s from drivers/pci/bus.c

[Kelsey Skunberg]

pci_bus_get() and pci_bus_put() are not used by a loadable kernel module
and do not need to be exported. Remove lines exporting pci_bus_get() and
pci_bus_put().

Functions were exported in commit fe830ef62ac6 ("PCI: Introduce
pci_bus_{get|put}() to manage PCI bus reference count"). No found history
of functions being used by a loadable kernel module.

Applied with Greg's ack to pci/hide for v5.4, thanks!
