💖 NAME 💖

hey bestie, you're on the mux_verify_port(9) page in the Kernel API Manual, and we're about to make kernel serial-port business make sense 🎀

mux_verify_port — Verify the port information. That's the name, that's the job, periodt 💅

✨ SYNOPSIS ✨

the signature is literally this:

int mux_verify_port (struct uart_port *port , struct serial_struct *ser
);

🦋 ARGUMENTS 🦋

okay so there are two arguments, and they are both pointers — no cap:

• port — Ptr to the uart_port. main-character pointer energy fr.
• ser — Ptr to the serial information. also essential, obviously 🫶

🌸 DESCRIPTION 🌸

Verify the new serial port information contained within serinfo is suitable for this port type. that's it — it's giving "vibe check, but for port info" ✨ the function is making sure the new info inside serinfo is suitable for this port type, and that's the whole flex, lowkey 💜
