✨ usb4_port_device_remove — the Kernel API Manual glow-up ✨

okay bestie, so you found usb4_port_device_remove in the Kernel API Manual and you're like "what does this even do" — don't worry, I got you 💖 this one is short and sweet, like a little goodbye note for a USB4 port device.

🌸 NAME 🌸

usb4_port_device_remove — literally just removes the USB4 port device, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

void usb4_port_device_remove (struct usb4_port *usb4 );

that's it. that's the whole call. no return value, no drama, void and gone ✨

---

💅 ARGUMENTS 💅

• usb4 — the USB4 port device in question, your little main character 🫶

---

🔥 DESCRIPTION 🔥

so what actually happens? it unregisters the USB4 port device from the system. no cap, that's the move 💀

and here's the part that matters: the device will be released when the last reference is dropped. so it's not like, instant vanishing — it's more of a "you're unregistered but you can stay until everyone's done with you" situation. very respectful, honestly 👑

🌈 SEE ALSO 🌈

• the kernel file ./drivers/thunderbolt/usb4_port.c (iconic source material, go read it 💜)
• usb4_usb3_port_match(9)
• usb4_port_device_add(9)
• usb4_port_device_resume(9)

like, the whole friend group basically — add, resume, remove, they're all in the same file and they all slay in their own way ⭐

---

fr fr, this is a tiny function, but it's doing its job exactly right. no guessing, no extra behaviour, just unregister and let the reference counting handle the rest 🙈
