Yeah, I saw it, but I can't get excited about drivers trying to
correct delays.  I don't think this can be done automatically in a
reliable way, and so I expect that the few end users who are really
getting into the microseconds and nanoseconds will calibrate their
systems end to end, maybe even patching out this driver nonsense in
their kernels.

Having said that, I won't stand in the way of such driver stuff.
After all, who cares about a few microseconds time error one way or
the other?

Thanks,
Richard
