Hi Takashi-san
Thanks ! I confirmed that this solved my issue from kernel Oops.

OK, I'll cook up a proper patch and submit soon later.
Thanks
It's hard to say only from that... But judging from your description, it must be relevant with the stale DAPM setup that was left untouched at the previous driver unbind? That is, the driver doesn't fully initialize the hardware at probe.
Thanks. I noticed that my one board could re-bind without issue, but one board had issue. I want to debug it. Do you know which function returns error to user side ? # set_params is only used on soc-compress, but my driver doesn't use it.
You can try tracing that was recently added by Sakamoto-san. The error comes from the unavailable hw_params, that is, some hw_params setup narrowed too much.
Or, if it's about DPCM, it can be due to some stale setup in BE. What if you unload/reload the modules, not only rebind?
Thanks. I will check it
