From e019ef0c4f11a0acb79b89fb1e09c72197b42bbe Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 21 Dec 2009 16:27:49 -0800 Subject: [PATCH] drivers/block/mg_disk.c: use resource_size() Use resource_size() for ioremap. The ioremap appears to be passing the incorrect size for the platform resource. Unfortunately, I can't locate a user in mainline to verify this. Using resource_size should be the correct fix.
