From 886a451bd2491de3551c2aea2a2f155f159716c8 Mon Sep 17 00:00:00 2001 From: David Brown Date: Tue, 2 Aug 2011 09:02:49 -0700 Subject: [PATCH] msm_serial: Use relative resources for iomem Device tree iomem resources are only accessible by index, and not by name. The msm_serial devices always have either 1 or 2 iomem resources, that are always in the same order. Convert the platform_get_resource_byname into just platform_get_resource to facilitate device tree conversion.
