From 5bdd5ded95b3188d58ba43ac801b8849cbea1b16 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Fri, 14 May 2010 14:58:05 +1000 Subject: [PATCH] crypto: mv_cesa - Use resource_size Use the resource_size function instead of manually calculating the resource size. This reduces the chance of introducing off-by-one errors.
