Subject: drm/radeon/kms: don't enable connectors that are off in the
hotplug handler
From: Alex Deucher <alexander.deuc...@amd.com>
commit 73104b5cfe3067d68f2c2de3f3d4d4964c55873e upstream.
If we get a hotplug event on an connector that is off, don't
attempt to turn it on or off, it should already be off.
