uart_match_port(9)

💅 uart_match_port(9) — like, the Kernel API Manual moment of "are you two the same port or not"

okay so bestie, buckle up 🎀 this one's from the Kernel API Manual, and it's a tiny little function with a huge "wait, are you actually the same person?" energy. It's called uart_match_port and honestly? It ate. ✨

---

🌸 NAME 🌸

uart_match_port — are the two ports equivalent? 👀 like, literally, is it the same port or not, no cap.

---

🦋 SYNOPSIS 🦋

bool uart_match_port (const struct uart_port *port1 , const struct
uart_port *port2 );

It returns a bool, bestie. That's it. That's the whole vibe check. 💖

---

✨ ARGUMENTS ✨

• port1 — the first port, aka the first contestant in this Are You The One episode 🫶
• port2 — the second port, aka the one we're holding up next to it like "hmm, twins?" 🔥

---

💜 DESCRIPTION 💜

so this utility function is the one you call when you need to determine whether two uart_port structures describe the same port. That's it. That's the whole job. It's giving "small but iconic side character who shows up, drops one crucial line, and leaves." 👑

No extra lore, no secret tricks, no "well actually" — it just tells you if these two structs are describing the same port. periodt. 💅

lowkey a reminder bestie: this page is literally just "are these two the same port" — don't go reading extra powers into it, iykyk 💀

and that's a wrap, gorgeous 💖 this little love letter lives over in ./drivers/tty/serial, and it's stamped October 2026 — so go forth, match those ports, slay, and remember: the vibes are immaculate and the bool is boolean. 🍓👑⭐
