From e2f55b54556ae6a3a365afead6bc8e46a2013d7f Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 27 Dec 2011 14:16:12 +0000 Subject: [PATCH] video: s3c-fb: Don't keep device runtime active when open Allow the controller to be runtime suspended when the screen is blanked by not taking a runtime reference while the device is open. This allows greater system wide power savings when used with a standard application layer and ensures that the screen does not blank unless requested.
