Is there any problems with that attr and drivers not being able to handle
the timeouts someone sets in sysfs. I mean if in my slave_configure I set
60 secs becuase for some reason my HW takes this long no matter what, someone
can reset this to 5 or 1 sec and there are is chance for the lld to override
this if it is invalid. Is this just one of those things where we say
only touch the timeout if you know what you are doing, or is it that the lld
should not have that power, or sometihng else?
