Does sound card registration failure at boot time due to modules

No, this is totally normal. If it failed to bind ever then that'd be a
problem but this is just deferring.
In that case, we don't need this work around I guess.
At maximum during boot time, we may see few sound card registration
failure logs,
Which is normal.
With this change, our concept of ACP parent device which will create
platform devices
for DMA driver, Generic DMIC driver and Machine driver will be changed.
We implemented same design for Raven I2S driver as well which got
productized.
OK, got it. It doesn't affect the sound function anyway.
BTW, so far, I have not seen the -517 error from ubuntu kernel dmesg on
PC or laptop. Maybe this is the 1st driver to print this error in the
dmesg on PC or laptop, so I guess it probably confuses the users or our QA.
