From that point,\nsnd_card_free(sc) releases cobsc through the ALSA card cleanup path.\n\nIf cobalt_alsa_init() fails after snd_cobalt_card_create(), the\nerr_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That\nsecond free releases the same object again.\n\nRemove the explicit kfree(cobsc) and leave ownership with the ALSA card.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review."
