BTW, we found ALSA SoC bind/unbind issue on latest upstream kernel. ALSA SoC is using like this.
[CPU] - [CARD] - [CODEC]
If we unbind CPU here, it still has CARD infomation. And, kernel doesn't call initialize function when re-bind, and it will panic when playback
Is this open bug ? Or, Renesas sound only ? fsi/rsnd both have this issue.
I'm not aware of anything here - when we rebuild the card we should be reinitializing everything. It's possible this is just broken for everyone though, most people don't unload devices and where they do they tend to remove the card first.
