This should not happen in production systems but we should test for
all callback arguments before invoking the config_stream callback.
so you are saying callback arg is mandatory, if so please document that
assumption
no, what this says is that if a config_stream is provided then it needs to
have a valid argument.
well typically args are not mandatory..
I am not sure what you mean by "document that assumption", comment in the
code (where?) or SoundWire documentation?
The callback documentation which in this is in include/linux/soundwire/sdw_intel.h
/**
* struct sdw_intel_ops: Intel audio driver callback ops
*
* @config_stream: configure the stream with the hw_params
*/
struct sdw_intel_ops {
int (*config_stream)(void *arg, void *substream,
void *dai, void *hw_params, int stream_num);
};
all parameters are mandatory really, not sure what you are trying to get at.
