| Subject: drm/i915/sdvo: Fully translate sync flags in the dtd->mode conversion |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| Instead of just a flag bit for each of the positive/negative sync |
| modes drm actually uses a separate flag for each ... This upsets the |
| modeset checker since the adjusted mode filled out at modeset time |
| doesn't match the one reconstructed at check time (since the |
| ->get_config callback already gets this right). |
