[alsa-devel] [PATCH] twl6040: fix wrong kfree in twl6040_remove and twl6040_codec_remove

[Axel Lin]

Memory allocation part:
We allocate a memory in twl6040_codec_probe():
        priv = kzalloc(sizeof(struct twl6040_data), GFP_KERNEL);
        twl6040_codec = codec = &priv->codec;

Memory release part:
In twl6040_codec_remove() we should kfree(priv) instead of kfree(twl6040_codec).
In twl6040_remove(), no need and should not kfree(codec).
