NACK! I said the approach of dropping "timeout" is OK, but unless I say
"you may add my ack after changing this and that", please do not
automatically add my ack. Doesn't hurt here, since I have to pick it up
anyway.

Thanks, I just noticed. Please drop (more precise: remove) the
"slave-addr" for the same reasons as "timeout". Doesn't make much sense
anyhow, pnx doesn't have any slave support.

I know that checkpatch complains about this, but I'd prefer to avoid
such changes unless the code before was really unreadable.
