When num_kcontrols is zero, widget->dobj.widget.kcontrol_type
gets set to an uninitialized local variable:
sound/soc/soc-topology.c: In function 'soc_tplg_dapm_widget_create':
sound/soc/soc-topology.c:1566:36: error: 'kcontrol_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I could not figure out which of the valid types would be appropriate
here, so this sets it to '0', which is invalid but at least well-defined
here. There is probably a better way to address the issue.
