All patches I did not comment are: Acked-by: Sam Ravnborg <sam@xxxxxxxxxxxx> I see why you introduced _unlocked, and remove it again. So you could ask the compiler to help you. But I see this as something that should not be committed and only part of your own tree. But thats not something I feel too strong about - let's just say it confused me a lttle. The driver patches was only skimmed, as they were mechanical anyway.
