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.
