✨ NAME ✨

coresight_select_best_sink — return the best sink for use as default from the two provided.

---

🫶 SYNOPSIS 🫶

struct coresight_device * coresight_select_best_sink (struct
       coresight_device *sink , int *depth , struct coresight_device *new_sink
       , int new_depth );

---

🎀 ARGUMENTS 🎀

• sink — the current best sink. like the reigning champ 💅
• depth — the search depth where the current sink was found.
• new_sink — the new sink that's getting compared against the current sink.
• new_depth — the search depth where the new sink was found.

---

🦋 DESCRIPTION 🦋

Sinks get prioritised according to coresight_dev_subtype_sink, and only subtypes CORESIGHT_DEV_SUBTYPE_SINK_BUFFER or higher are used. no cap.

When two sinks have equal priority, the sink closest to the source wins — that means the smallest search depth. iconic behavior honestly 🌸

The return vibe is: return new_sink & update depth if it's better than sink, else return sink. periodt. 💫
