I'm confused. Just because a distro/product includes patches in their tree, does not mean they are all applicable for stable kernel releases. Adding new device support in ways that is not just a simple quirk or other table addition, isn't ok. So this clk series isn't ok. I'm going to drop this whole patch series now. Can you please review it, and resend any that you think are applicable? thanks, greg k-h
