sound: usb: make the USB MIDI module more independent
Remove the dependecy from the USB MIDI code on the snd_usb_audio structure. This allows using the USB MIDI module from another driver without having to pretend to be the generic USB audio driver. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
