From 7c3ed0fd9b72d489243ff97f3cea2e1d4d07d9fa Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 20 May 2011 04:34:30 -0400 Subject: [PATCH] drm/radeon/kms: bail early for eDP in hotplug callback Don't try and en/disable the port as it may be a hpd event from powering up/down the panel during a modeset or dpms.
