2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Keith Packard <[email protected]> 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.
