3.6.11.6 stable review patch. If anyone has any objections, please let me know.
------------------ From: Egbert Eich <[email protected]> [ Upstream commit 53d3b4d7778daf15900867336c85d3f8dd70600c ] In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC. Thus the code will always have to rely on a LVDS panel mode supplied by VBT. In most cases this succeeds, so this didn't get detected for quite a while. This regression seems to have been introduced in commit f899fc64cda8569d0529452aafc0da31c042df2e Author: Chris Wilson <[email protected]> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links Signed-off-by: Egbert Eich <[email protected]> Cc: [email protected] Reviewed-by: Chris Wilson <[email protected]> Signed-off-by: Steven Rostedt <[email protected]> [danvet: Add note about which commit likely introduced this issue.] Signed-off-by: Daniel Vetter <[email protected]> --- drivers/gpu/drm/i915/intel_sdvo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_sdvo.c b/drivers/gpu/drm/i915/intel_sdvo.c index d554f64..95c0433 100644 --- a/drivers/gpu/drm/i915/intel_sdvo.c +++ b/drivers/gpu/drm/i915/intel_sdvo.c @@ -1603,7 +1603,7 @@ static void intel_sdvo_get_lvds_modes(struct drm_connector *connector) * Assume that the preferred modes are * arranged in priority order. */ - intel_ddc_get_modes(connector, intel_sdvo->i2c); + intel_ddc_get_modes(connector, &intel_sdvo->ddc); if (list_empty(&connector->probed_modes) == false) goto end; -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
