ASoC: avoid duplicated DAI routes
ASoC automatically creates snd_soc_dapm_dai_in and snd_soc_dapm_dai_out
widgets for DAI drivers, and adds them to the list. Later on, ASoC
creates automatic routes between these widgets and a widget with a
stream name.
We look for a snd_soc_dapm_dai_in or snd_soc_dapm_dai_out widget, and
use this to obtain the DAI structure. We then scan all widgets for
any with a stream name refering to either the capture or the playback
stream, and create routes.
If you have both a snd_soc_dapm_dai_in and a snd_soc_dapm_dai_out
referring to the same DAI structure, this ends up creating one set of
routes for the DAI for the snd_soc_dapm_dai_in widget, and a duplicated
set of routes for the snd_soc_dapm_dai_out widget.
Fix this by checking that the stream name for the widget matches the
DAI widget name.
