This is with a new driver that just went into -next and I was trying a suggestion from Daniel to re-order the initialisation steps in preparation of the series that Chris Wilson is working on to make init time less racy. It is not a normal run splat and I will make sure that we work with you to get tda998x changed when we get there. Other than the ticlcd driver that is (I think) being converted to atomic, do you use any other DRM driver with tda998x?
