From 73db4bedc5dde97adf59b5b5a07c6cf0ee56e668 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 26 May 2010 10:41:45 +1000 Subject: [PATCH] drm/nouveau: don't execute INIT_GPIO unless we're really running the table This resulted in accidently switching off the eDP panel on certain laptops since the default state in the GPIO table was off.
