Call snd_soc_dapm_new_widgets() before the auto non-connected pins have been marked as not connected will power the system under the assumption that those pins are connected. Once the pins have been marked as disconnected the system there will be an additional power run. This can cause unnecessary power transitions. Calling snd_soc_dapm_new_widgets() only after the pins have been marked as non-connected avoids this.
