From 68003e6cf2bbd239a322bd8a28dacfaf8174fdee Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Thu, 31 Dec 2015 16:40:43 +0800 Subject: ASoC: Support registering a DAI dynamically Define API snd_soc_register_dai() to add a DAI dynamically and create the DAI widgets. Topology can use this API to register DAIs when probing a component with topology info. These DAIs's playback & capture widgets will be freed when the sound card is unregistered and the DAIs will be freed when cleaning up the component. And a dobj is embedded into the struct snd_soc_dai_driver. Topology can use the dobj to find the DAI drivers created by it and free them when the topology component is removed.
