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).
