okay so this is a page from the Kernel API Manual, bestie — yes, the actual kernel, and yes, you're gonna get it 💅

---

💖 NAME 💖

coresight_clear_default_sink — literally removes every default sink reference pointing at the sink you hand it. all of them. gone. periodt.

---

🦋 SYNOPSIS 🦋

void coresight_clear_default_sink (struct coresight_device *csdev );

---

🎀 ARGUMENTS 🎀

• csdev — the coresight sink in question 🫶 take this one and remove all the references to it from, like, every source. it's giving cleanup era.

---

🌸 DESCRIPTION 🌸

so here's the vibe check: if the device you handed over is actually a sink, then it goes through all the bus devices and clears out every single reference to this sink from the coresight_device def_sink parameter. no cap, that's the whole thing 💀

basically: sink detected → references yeeted → def_sink is clean ✨
