From 132390c79e01b3da732bc7b5d9e729b52086ceb6 Mon Sep 17 00:00:00 2001 From: Andy Gross Date: Mon, 5 Mar 2012 10:48:37 -0600 Subject: [PATCH] staging: drm/omap: Disable DMM debugfs for OMAP3 OMAP3 does not contain a DMM/Tiler block. As such, we should not be exposing any DMM debugfs entries on OMAP3 platforms. Added inline helper function to verify existence of DMM.
