Subject: [PATCH 1/4] PCI: Add empty stub for pci_register_io_range()
Date: Thu, 27 May 2021 14:45:44 -0500 [thread overview]
Message-ID: <20210527194547.1287934-2-robh@kernel.org> (raw)
In-Reply-To: <20210527194547.1287934-1-robh@kernel.org>
Add an empty stub for pci_register_io_range() when !CONFIG_PCI. It's needed
to convert of_pci_range_to_resource() to use IS_ENABLED(CONFIG_PCI).
