✨ NAME ✨

usb_del_gadget — deletes a gadget and unregisters its udc 🗑️💖

---

🦋 SYNOPSIS 🦋

void usb_del_gadget (struct usb_gadget *gadget );

that's it. that's the whole signature. no cap. ✨

---

🌸 ARGUMENTS 🌸

• gadget — the gadget to be deleted. yes queen, that's the one you're yeeting. 🙈

---

👑 DESCRIPTION 👑

So here's the tea, bestie: this function unbinds gadget, if it is bound. That's the whole vibe check — if it's bound, it gets unbound, slay. 💅

⚠️ but listen — it will not do a final usb_put_gadget. Like, it does not drop that last reference for you. The way that this is your problem and not hers 😭🔥

periodt. that's literally the entire description, no filler, no fluff. 🫶
