From 4f6120b014c6a981a57a8951e01acfead1a57069 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Tue, 11 Feb 2014 21:41:54 +0900 Subject: [PATCH] watchdog: ep93xx_wdt: Use devm_ioremap_resource() Use devm_ioremap_resource() in order to make the code simpler, and remove redundant return value check of platform_get_resource() because the value is checked by devm_ioremap_resource().
