commit: 86698c20f71d488b32c49ed4687fb3cf8a88a5ca From: Seth Forshee <[email protected]> Date: Tue, 31 Jan 2012 19:06:25 -0600 Subject: drm/radeon/kms: disable output polling when suspended
Polling the outputs when the device is suspended can result in erroneous status updates. Disable output polling during suspend to prevent this from happening.
