From 6e58ed578e2c65442b7a02deecc96e482c701654 Mon Sep 17 00:00:00 2001 From: Andrzej Pietrasiewicz Date: Thu, 16 Oct 2014 13:33:25 +0200 Subject: [PATCH] usb: gadget: f_midi: enable use of the index parameter 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).
