From 3f33647c41962401272bb60dce67e6094d14dbf2 Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Tue, 26 Jan 2016 21:57:29 +0100 Subject: resource: Add walk_iomem_res_desc() Add a new interface, walk_iomem_res_desc(), which walks through the iomem table by identifying a target with @flags and @desc. This interface provides the same functionality as walk_iomem_res(), but does not use strcmp() to @name for better efficiency. walk_iomem_res() is deprecated and will be removed in a later patch.
