Subject: [PATCH v3 07/25] PCI: iproc: Use pci_parse_request_of_pci_ranges()
Date: Mon, 28 Oct 2019 11:32:38 -0500 [thread overview]
Message-ID: <20191028163256.8004-8-robh@kernel.org> (raw)
In-Reply-To: <20191028163256.8004-1-robh@kernel.org>
Convert the iProc host bridge to use the common
pci_parse_request_of_pci_ranges().
There's no need to assign the resources to a temporary list, so just use
bridge->windows directly.
