Simple mutex_destroy question

Hi, Do I need to call mutex_destroy in a failed probe exit, or in the remove module function, if the mutex is located in memory allocated with devm_kzalloc and family? Like: static int mychip_i2c_probe(struct i2c_client *client) {     struct chip *chip;     int ret;     chip = devm_kzalloc(&client->dev, sizeof(*chip), GFP_KERNEL);     if (!chip)         return -ENOMEM;     mutex_init(&chip->lock);     i2c_set_clientdata(client, chip);     /* Do my chip stuf     */     return ret; probe_fail:     mutex_destroy(&chip->lock);     return ret; } I understand that mutex_destroy will only invalidate the memory, but as I am freeing this is not necessary?
