✨ usb_composite_unregister(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a shortie but a goodie — it's the breakup function for composite drivers 🫶

---

🌸 NAME 🌸

usb_composite_unregister — unregister a composite driver 💅

---

🎀 SYNOPSIS 🎀

void usb_composite_unregister (struct usb_composite_driver *driver );

that's it. that's the whole signature. no return value, it just hands in the resignation letter 😭

---

🦋 ARGUMENTS 🦋

• driver — the driver to unregister. literally the one getting un-registered. the main character of the breakup arc 💔

---

⭐ DESCRIPTION ⭐

so what does it do?? ngl it's pretty straightforward: this function is used to unregister drivers using the composite driver framework 🌈

like, you registered your driver with the composite framework, and now you're done, so you call this and it unregisters it. clean. simple. iconic 👑

no cap, there's genuinely nothing else in here — no hidden options, no weird edge cases spelled out. it does exactly what the name says 🍓
