Commit aafe77cc45a5 (ALSA: usb-audio: add support for many Roland/Yamaha
devices) had several logic errors that prevented create_auto_midi_quirk
from enumerating any MIDI ports.

I've just got around for testing this. Debug logfile at the bottom.
Playback and record interfaces are correctly listed:
$ aplay -l
...
card 3: JS8 [JS-8], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
$ arecord -l
...
card 3: JS8 [JS-8], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
This time, the MIDI interfaces are also listed:
$ amidi -l
Dir Device    Name
IO  hw:3,0,0  JS-8 MIDI 1
IO  hw:3,0,1  JS-8 MIDI 2
(By the way, I still have no idea what these MIDI ports do, if anything. there 
seems to be no ooutput from the JS-8 MIDI, and it doesn't seem to respond to 
any of the MIDI events I have tried sending to it. It's possible it's used for 
some sort of Sysex, or maybe it's vestigial.)
I tested it with simultaneous playback and record using Ardour3 and it works 
great.
Cheers,
Keith
