Message-Id: <7e10d1bd6ca988c9deca593588e5b7fdd72a8de4.1525067324.git.jan.kiszka@siemens.com> Date: Mon, 30 Apr 2018 07:48:35 +0200 From: Jan Kiszka <jan.kiszka@...mens.com> To: Bjorn Helgaas <bhelgaas@...gle.com>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, linux-pci@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Subject: [PATCH v2 01/10] PCI: Make pci_get_new_domain_nr() static From: Jan Kiszka <jan.kiszka@...mens.com> 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.
