From bc5e6dea81b025aba8fecec5c18f6faf81db9562 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 21 Jan 2013 11:09:06 +0100 Subject: [PATCH] iommu: Convert to devm_ioremap_resource() Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.
