so if the rate is zero there is no error?
(stream->params.rate != stream_config->frame_rate)) {dev_err(dev, "rate not matching, stream:%s", stream->name);return -EINVAL;- }
- if ((stream->params.bps) &&
same here, what is the intent behind the first test?
IIRC this was to check for valid values, but am not too sure, let me get back to you on these two..
So if the value previously is not set, we want to allow it be set and then compare. We are not checking for zero value or wrong values here, we are checking fir values to be matched
Since you have asked this second time, I am going to add a comment here to clarify..
