These three declares are here: struct gbaudio_data_connection *data;
Since all three of these functions check for if the codec->module_list is empty at the start of the function so these are not real bugs to bypass 'if (!data) {'. To avoid static checker warnings like Smatch, initialize the data with NULL.
