drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC.
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 <chris@chris-wilson.co.uk> Date: Tue Jul 20 15:44:45 2010 -0700 drm/i915: use GMBUS to manage i2c links Signed-off-by: Egbert Eich <eich@suse.de> Cc: stable@vger.kernel.org Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> [danvet: Add note about which commit likely introduced this issue.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
