cdns_uart_release_port(9)

✨ cdns_uart_release_port — Release UART port ✨

okay so bestie, you're in the section 9 part of the Kernel API Manual 🎀 and this is the page for cdns_uart_release_port. it's a lil function, it does one thing, and honestly? it slays at that one thing. 💅

---

🌸 SYNOPSIS 🌸

void cdns_uart_release_port (struct uart_port *port );

returns nothing (void, she gives nothing and takes everything 💀) and it takes exactly one arg. no cap.

---

🦋 ARGUMENTS 🦋

• port — the handle to the uart port structure. that's it. that's the whole vibe. it's your little pointer bestie to the port you're about to set free 🫶

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — cdns_uart_release_port releases the memory region attached to a cdns_uart port. that's the whole job, and she does it iconically.

when does it get called? when the driver removes a cdns_uart port via uart_remove_one_port. so it's like the goodbye-hug function for a port's memory region 🌈 and yes, it's literally the cleanup queen we deserve 👑
