Maybe but note that drm-next just complains that there's no modes:
"Connected connector with 0 modes"
whereas 2.6.31 kernel reports this too, but also says it's fallbacking
on standard modes:
i2c-adapter i2c-0: unable to read EDID block.
radeon 0000:02:00.0: VGA-1: no EDID data
[drm:drm_helper_initial_config] *ERROR* connectors have no modes, using
standard modes
IMHO, the culprit would be that chunk:
diff --git a/drivers/gpu/drm/drm_crtc_helper.c b/drivers/gpu/drm/drm_crtc_helper.c
index 6aaa2cb..ff447f1 100644
