sof_set_widget_pipeline(9)

💖 NAME 💖

okay so this is sof_set_widget_pipeline(9) from the Kernel API Manual, and the whole NAME vibe is literally: set pipeline for a component 💅 no cap, that's the assignment.

✨ SYNOPSIS ✨

int sof_set_widget_pipeline (struct snd_sof_dev *sdev , struct
       snd_sof_pipeline *spipe , struct snd_sof_widget *swidget );

🎀 ARGUMENTS 🎀

• sdev — pointer to struct snd_sof_dev, aka the device situation bestie 🫶
• spipe — pointer to struct snd_sof_pipeline, the pipeline in question ✨
• swidget — pointer to struct snd_sof_widget that has the same pipeline ID as pipe_widget 👑

🌸 RETURN 🌸

• 0 if successful 🎉
• -EINVAL on error 😭

Also important, and I'm saying this with love: the function checks if swidget is associated with any volatile controls. If so, setting the dynamic_pipeline_widget is disallowed. That's the rule, bestie 💅
