All patches I did not comment are:
Acked-by: Sam Ravnborg <sam at ravnborg.org>
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.
