You don't get that option with latency.c either at the moment, and it's
arguable whether it's even worth it. The more curious thing is that while
this qos params seems to be an evolution of Arjan's latency.c (and the
drivers that are using it are updated in the rest of the patch set),
latency.c itself is still compiled in. Is this an oversight, or was it
intentional? One set of latency hinting APIs only, please :-)
