Technically there are still some maintainers' ack missing but I'd really
like to get this series applied. As I don't want to make people angry
I'm asking once more for your Acks.

Or is the stuff outside of drivers/amba trivial enough to merge it even
without each maintainer's ack? (It's changing some functions from
returning int to void and dropping "return 0;".)

Best regards
Uwe
