NOTE: this patch isn't required for correctness but instead optimizes probe order / helps avoid deferrals. Acked-by: Rob Herring Signed-off-by: Douglas Anderson --- Since this is so small, I'd presume it's OK for it to go through a DRM tree with the proper Ack. That being said, this patch is just an optimization and thus it could land completely separately from the rest and they could all meet up in mainline.
