From e40b6fc8373314666e7853733dc0ca4049a68b95 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 18 Feb 2011 15:51:57 +1000 Subject: drm/radeon/kms: align height of fb allocation. this aligns the height of the fb allocation so it doesn't trip over the size checks later when we use this from userspace to copy the buffer at X start.
