From 3c86c07baaa22e1ebae1922b5285f79a39e93d83 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 14 Apr 2011 21:09:16 +0900 Subject: [PATCH] USB: ohci-s3c2410: use resource_size() This patch uses the resource_size help function instead of manually calculating the resource size. It can reduce the chance of introducing off-by-one errors.
