I think that's just copy and paste and it is a useless check given
that the only way we can set that flag on ARM/ARM64 is through DT
(of_pci_check_probe_only()) and I doubt that systems probing this
driver really require a PCI_PROBE_ONLY set-up.
So, unless you can explain to us why it is really needed, please
remove the:
if (!pci_has_flag(PCI_PROBE_ONLY))
check.
