The freed list is created by dapm_widget_list_create() (B) which is called from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from dpcm_path_get() (D). (B) dapm_widget_list_create(**list, ...) { ... => *list = kzalloc(); ... } (C) snd_soc_dapm_dai_get_connected_widgets(..., **list, ...) { ... dapm_widget_list_create(list, ...); ... } (D) dpcm_path_get(..., **list) { ... snd_soc_dapm_dai_get_connected_widgets(..., list, ...); ... } (A) dpcm_path_put(**list) { => kfree(*list); } This kind of unbalance code is very difficult to read/understand. To avoid this issue, this patch adds each missing paired function dapm_widget_list_free() for dapm_widget_list_create() (B), and snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C). This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().
