Thanks.

ALSA rawmidi core handles substreams for both directions, therefore 
state management may not so simple as we expected (at least, for driver 
based on packet streaming such as IEC 61883-1/6, there're more items to 
be considered. So as USB MIDI Device class, too, I think). I'd like to 
schedule the work to next developing cycle for Linux 4.7 or later.
