Currently new widgets are appended to the beginning of the cards widget list. This has the effect that widgets that are created while iterating over the widget list in snd_soc_dapm_new_widgets() (like e.g. the auto-disable widgets) are not covered during that invocation of the function. If no further invocations of snd_soc_dapm_new_widgets() happen these widgets will not be fully initialized and e.g. no debugfs entries are created for them.
By adding new widgets to the end of the widget list we make sure that widgets that are created in snd_soc_dapm_new_widgets() will still be handled during the same snd_soc_dapm_new_widgets() invocation and are always fully initialized.
