4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> [ Upstream commit 83c75ddd816e979802bd244ad494139f28152921 ] 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.
