From 811aaa55ba21ab37407018cfc01770d6b037d3fb Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Thu, 3 Feb 2011 16:57:28 -0800 Subject: [PATCH] drm: Only set DPMS ON when actually configuring a mode In drm_crtc_helper_set_config, instead of always forcing all outputs to DRM_MODE_DPMS_ON, only set them if the CRTC is actually getting a mode set, as any mode set will turn all outputs on.
