parport_put_port(9)

💅 parport_put_port(9) 💅

ok so bestie, welcome to the Kernel API Manual — specifically the page for parport_put_port. this is the "i'm done with you now, bye" function for parallel ports, and yes it's as iconic as it sounds 🎀

---

✨ NAME ✨

parport_put_port — decrement a port's reference count 🫶

like, you picked the port up, now you're putting it back down. politeness in kernel form, fr fr.

---

🌸 SYNOPSIS 🌸

void parport_put_port (struct parport *port );

void return, so nothing comes back at you — it's giving "no receipts needed" energy 💅

---

🦋 ARGUMENTS 🦋

• port — the port 💖 (that's it, that's the argument, she's simple and she's iconic)

---

⭐ DESCRIPTION ⭐

okay so here's the whole vibe: you should call this once for each call to parport_get_port, once the port is no longer needed. one call out for every call in, no cap — that's the whole contract 🔥

and then the main character moment: when the reference count reaches zero (aka the port is no longer used by literally anyone), free_port is called. so the port gets its little farewell arc 😭✨

yes this means you can't just skip it. the port is waiting to be freed and you're the one holding up the show 🙈
