This commit doesn't change the widget name, only the widget type. My commit
message did not make that clear.

This was one of the first patches I wrote. Now that I understand DAPM better, I
realize that it has no functional impact, and this shouldn't go to stable.
(snd_soc_dapm_aif_in and snd_soc_dapm_aif_out are handled exactly the same, so
fixing the widget type is, as you say, just a textual cleanup.)
