From dae4d1ddb352a0c240575886bb7b3920b3a8cafc Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Mon, 4 Mar 2013 14:36:27 +0530 Subject: [PATCH] dma: pl330: Convert to devm_ioremap_resource() Use the newly introduced devm_ioremap_resource() instead of devm_request_and_ioremap() which provides more consistent error handling.
