✨ NAME ✨

hid_quirks_exit — literally the function that frees all the memory hanging out with dynamic_quirks. it's giving ✨closure✨ 💅

---

🦋 SYNOPSIS 🦋

void hid_quirks_exit (__u16 bus );

that's it. that's the whole vibe check. returns nothing, takes one little bus and sends those quirks home. 🎀

---

💜 ARGUMENTS 💜

• bus — a bus to match against. that's the one she's coming for. 🫶

---

🌈 DESCRIPTION 🌈

so the way that this works is: hid_quirks_exit releases all the memory associated with dynamic quirks for a given bus. every last byte. she does not leave crumbs. 🧚

she's called upon module unload — like when the module is packing its bags and heading out, this is the friend who makes sure the lights are off and the door's locked. 😭

and here's the iconic part: if you pass HID_BUS_ANY, she removes all dynamic quirks. every bus, every quirk, gone. main character energy fr fr. 🔥

---

👑 RETURN 👑

nothing. zero. nada. she gives and gives and asks for no return value in exchange. 💀

ngl bestie, "nothing" is the whole return value. don't go looking for a 0 or an -EINVAL, it's not there. 🙈
