1) In 2.6.38, after these 2 operations:
snd_soc_dapm_new_controls(dapm, dapm_widgets, ARRAY_SIZE(dapm_widgets));
snd_soc_dapm_add_routes(dapm, audio_map, ARRAY_SIZE(audio_map));
Is it *always* necessary to call snd_soc_dapm_new_widgets(dapm)?
I have seen one case where it was not called.
2) In 2.6.39, to do the same, is there any function to call other than the table entries?
Thanks,
Peter

It's not actually required for CODEC drivers, the core will run it when
probe finishes.

Not for the DAPM init.
