From: Jan Kiszka The only user of pci_get_new_domain_nr() is of_pci_bus_find_domain_nr(). Since they are defined in the same compilation unit, pci_get_new_domain_nr() can be made static, which also simplifies preprocessor conditionals. No functional change intended. Signed-off-by: Jan Kiszka A

[PATCH v3 6/8] PCI: Rework of_pci_get_host_bridge_resources() to devm_of_pci_get_host_bridge_resources()
