From 38013262c2c815fa404fa9f42dbc958c616fb385 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 22 Mar 2010 02:11:45 +0000 Subject: [PATCH] korina: use resource_size() This size calculation is wrong. It should be end - start + 1. Use resource_size() to calculate it correctly. Signed-off-by: Dan Carpenter Signed-off-by: David S.
