Hi Dan
Thank you for reporting about this.
I think this issue was solved by this patch which is in mark/fix/rcar
0ea617a298dcdc2251b4e10f83ac3f3e627b66e3
("ASoC: rsnd: don't double free kctrl")
> The patch d1f83d6ef43b: "ASoC: rsnd: call missing snd_ctl_remove()"
> from Feb 2, 2015, leads to the following static checker warning:
>
> sound/soc/sh/rcar/core.c:1034 __rsnd_kctrl_new()
> error: double free of 'kctrl'
>
> sound/soc/sh/rcar/core.c
> 1026 int ret;
> 1027
> 1028 kctrl = snd_ctl_new1(&knew, mod);
> 1029 if (!kctrl)
> 1030 return -ENOMEM;
> 1031
> 1032 ret = snd_ctl_add(card, kctrl);
> 1033 if (ret < 0) {
> 1034 snd_ctl_free_one(kctrl);

> The snd_ctl_add() function frees kctrl on error. It's a confusing
