From ee352c272e41c67aac887cbfd8c6aa71e5721997 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 28 Oct 2019 11:32:45 -0500 Subject: PCI: xilinx: Use pci_parse_request_of_pci_ranges() Convert the Xilinx host bridge to use the common pci_parse_request_of_pci_ranges(). There's no need to assign the resources to a temporary list first. Just use bridge->windows directly and remove all the temporary list handling.
