From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
dai / component related resources are created when component is registered, and it will be freed when component was unregistered. These resources are not re-used after that. This means, we can use devm_xxx for dai / component, without thinking about kfree(). This patch uses devm_xxx for these.
