Static function dal_ddc_i2c_payloads_destroy is only called in dal_ddc_service_query_ddc_data, the parameter is &payloads , there is no point NULL risk, so no need to check. This change is to make the code run a bit fast.
How about just getting rid of dal_ddc_i2c_payloads_destroy() and just call dal_vector_destruct() directly.
Good idea, I will resubmit a patch, thanks!
