f_midi_bind_config - add USB MIDI function to a configuration : the configuration to supcard the USB audio function : the soundcard index to use for the ALSA device creation : the soundcard id to use for the ALSA device creation : the buffer length to use the number of read requests to pre-allocate Context: single threaded during gadget setup

Returns zero on success, else negative errno.
