The soundcard index to use for the ALSA device creation is passed as a parameter to f_midi_bind_config(), but is assigned to midi->index only after the call to f_midi_register_card(midi). So no matter what is passed to f_midi_bind_config(), the actual index for snd_card_new() is always 0. This probably works ok if at the moment of f_midi's bind there are no other snd_cards, but if there are, it is not possible to bind f_midi. This patch moves the assignment to a place before the call to f_midi_register_card(midi).
