Subject: [PATCH] drm: Only set DPMS ON when actually configuring a mode

commit 811aaa55ba21ab37407018cfc01770d6b037d3fb upstream.

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.

This fixes https://lkml.org/lkml/2011/1/24/457
