The "correct" approach is clearly to just have the drm core change the i2c mux before requesting edid, but that's made difficult because of the absence of ordering guarantees in initialisation. I don't like quirking this, since we're then back to the situation of potentially having to add every new piece of related hardware to the quirk list. -- Matthew Garrett | mjg59@srcf.ucam.org
