From 83c75ddd816e979802bd244ad494139f28152921 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 7 Dec 2017 11:15:20 +0100 Subject: PCI: rcar: Handle rcar_pcie_parse_request_of_pci_ranges() failures rcar_pcie_parse_request_of_pci_ranges() can fail and return an error code, but this is not checked nor handled. Fix this by adding the missing error handling.
