Hmm, to be honest, I always have difficulties with this "retries"
parameter; to me "try x milliseconds" makes more sense than "try 5
times". It is there for ages, so we have to stick with it, but frankly,
I wouldn't like to expose it too much :)

I'm okay with the original patch putting some "sane" initial value. It
can be modified at runtime via a i2c-dev ioctl if needed.
