[PATCH v2 14/21] drm/i915/dp: Disable link retraining after the last fallback step

2024-05-20 Thread Imre Deak
After a link training failure if the link parameters can't be further reduced, there is no point in trying to retrain the link in the driver. This avoids excessive retrain attempts after detecting a bad link, for instance while handling MST HPD IRQs, which is likely redundant as the link training f
