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. Signed-off-by: Russell King Signed-off-by: Mark Brown --- Reading git-diff-tree failed
