💅 sfp_bus_del_upstream(9) 💅

Okay so this is the Kernel API Manual entry for sfp_bus_del_upstream(9), and we're gonna get you comfy with it, bestie 🫶

---

✨ NAME ✨

sfp_bus_del_upstream — Delete a sfp bus. That's the name, that's the gig, and yes it's literally giving cleanup era 💅

---

🌸 SYNOPSIS 🌸

void sfp_bus_del_upstream (struct sfp_bus *bus );

---

🎀 ARGUMENTS 🎀

• bus — a pointer to the struct sfp_bus structure for the sfp module. Hand it over, bestie 💖

---

🦋 DESCRIPTION 🦋

So this function deletes a previously registered upstream connection for the SFP module. Like, it's the cleanup bestie to sfp_bus_add_upstream, no cap 😭

bus should have been added by sfp_bus_add_upstream. That's the expectation — so don't just roll in with some random bus, okay? It should have come from that add call first. 🙈
