From e0998eab678233fae7dff7b92db08ad0f01acf91 Mon Sep 17 00:00:00 2001 From: axel lin Date: Sat, 29 Jan 2011 09:35:45 +0000 Subject: [PATCH] video: sh7760fb: use resource_size() The size calculation is done incorrectly in request_mem_region because it should include both the start and end (end - start + 1).
