Peter Ujfalusi f6c0ebc10c ASoC: SOF: sof-audio: prepare_widgets: Check swidget for NULL on sink failure ... commit fb4293600c upstream. If the swidget is NULL we skip the preparing of the widget and jump to handle the sink path of the widget. If the prepare fails in this case we would undo the prepare but the swidget is NULL (we skipped the prepare for the widget). To avoid NULL pointer dereference in this case we must check swidget against NULL pointer once again.
