✨ dpll_pin_on_pin_unregister(9) ✨

okay bestie, this one lives in the Kernel API Manual and it's basically the "we're so done here" button for a dpll pin that's attached to a parent pin 🎀

---

💅 NAME

dpll_pin_on_pin_unregister — unregister a dpll pin from a parent pin. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS

void dpll_pin_on_pin_unregister (struct dpll_pin *parent , struct
       dpll_pin *pin , const struct dpll_pin_ops *ops , void *priv );

literally a void function, so don't go looking for a return value, there isn't one 💀

---

🌈 ARGUMENTS

• parent — pointer to a parent pin 👑 the main character pin, the one doing the parenting
• pin — pointer to a pin 🎀 the baby pin being unregistered from it
• ops — ops for a dpll pin ✨ yes, the struct dpll_pin_ops crowd
• priv — pointer to private information of owner 🙈 the owner's own little private stash

---

🔒 CONTEXT

Acquires a lock (dpll_lock) — so yeah, this one grabs the lock. noted. respect the lock. 🫶

---

💀 NOTE

It does not free the memory. like, at all. this function is not your cleanup crew, bestie. don't come crying to me when you leak — that's on you 😭
