I'm holding off on this one. I'm applying the LVDS caching (makes complete sense) but I think someone needs to take a serious look at the requests for modes on outputs by the kernel and be sure that we've separated "I want you go to reprobe and then tell me the current data" from "tell me what the current set of modes is." Once that's done, I expect this patch goes away. -- Eric Anholt [email protected] [email protected]
