💅 tty_port_unregister_device(9) — NAME

okay so bestie, welcome to the Kernel API Manual, section 9, and this little icon is literally called tty_port_unregister_device — it deregisters a tty or serdev device 🎀

Like, it's the breakup function. We registered, now we un-register. Closure, but in kernel land. 💔✨

✨ SYNOPSIS ✨

void tty_port_unregister_device (struct tty_port *port , struct
tty_driver *driver , unsigned index );

yep that's it, that's the whole vibe check — no cap 👑

🫶 ARGUMENTS 🫶

  • port — the tty_port of the device, aka the main character of this whole situation 🦋
  • driver — the tty_driver for this device, its ride-or-die 💖
  • index — the index of the tty, the little number that tells you which one 🎀

🌸 DESCRIPTION 🌸

so ngl, here's the tea: if a tty or serdev device got registered with a call to tty_port_register_device_serdev, then this function must be called when the device is gone. periodt. 💅

not me emphasizing that — it's a must, not a "whenever you feel like it" 😭 take it seriously bestie, the device is gone, you gotta clean up after it 🧹✨

💜 SEE ALSO 💜

the kernel file lives at ./drivers/tty/tty_port.c and here's the whole friend group, all of them, no one left out 🫶🌈:

sign-off time 🎀✨

this diva came to you from ./drivers/tty, dated October 2026, and it's the tty_port_unregister_device(9) era 💖 go forth and unregister responsibly, ily, bye 🦋💅
