Hi Johannes,
pci_stop_and_remove_bus_device() is available on kernel 3.10, but this
code does a pci_uock_rescan_remove() and pci_unlock_rescan_remove()
around it and this was added in kernel 3.14, see here:
https://git.kernel.org/linus/9d16947b75831acd317ab9a53e0e94d160731d33
As this is currently only used for the ath9k owl loader and only causes
problems on kernel < 3.14 I did not care much about this.
Hauke
