From e3dc17a53f9649d0a67ec69ec883e781fa9dd920 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 9 Apr 2015 14:36:52 -0500 Subject: [PATCH] PCI: layerscape: Simplify platform_get_resource_byname() failure checking devm_ioremap_resource() validates the resource it receives, so if we check for devm_ioremap_resource() failure, we need not check for failure of the preceding platform_get_resource().
