[PATCH] greybus: audio_codec: initialize data to silence static checker warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
