🌸 SYNOPSIS 🌸

void serial_core_remove_one_port (struct uart_driver *drv , struct uart_port *uport );

---

🦋 ARGUMENTS 🦋

• drv — pointer to the uart low level driver structure for this port. it’s giving “who’s your driver bestie” energy. 💖
• uport — uart port structure for this port. literally the port in question. 👑

⭐ CONTEXT ⭐

task context, might sleep 😴 — so like, act accordingly, bestie.

🔥 DESCRIPTION 🔥

This unhooks the specified port structure from the core driver — and hangs it up too, no cap. once that’s done, no further calls will be made to the low-level code for this port. periodt. 💅

The caller must hold port_mutex 🔒 — that is not a vibe suggestion, it’s the rule. fr fr.
