💅 rmi_registe...sport_device(9) — a Kernel API Manual moment ✨

okay bestie, gather round, because today we're talking about a page from the Kernel API Manual and honestly? it's giving "small function, big responsibilities" 🎀

🌸 NAME 🌸

rmi_register_transport_device — bestie, this one registers a transport device connection on the RMI bus. and like, what does that even mean? okay so: transport drivers are the ones that provide communication from the devices on a bus (think SPI, I2C, and so on, the whole little crew) over to the RMI4 sensor. that's the vibe. that's the whole job. 💫

✨ SYNOPSIS ✨

int rmi_register_transport_device (struct rmi_transport_dev *xport );

like yes, that's the whole signature, no cap. returns an int, takes one pointer, we move. 🫶

🦋 ARGUMENTS 🦋

• xport — the transport device to register. that's it. that's the argument. she's the main character of this function call, so hand her over and let her slay. 👑

🔥 SEE ALSO 🔥

• Kernel file ./drivers/input/rmi4/rmi_bus.c — the actual source, go read it, iykyk 📖
• rmi_unregister_transport_device(9) — the reverse move, the "we're so done here" energy
• __rmi_register_function_handler(9) — handler registration, the double-underscore edition
• rmi_unregister_function_handler(9) — and its undoing, as one does

ngl bestie, this page is short but she's iconic — register your transport device, keep the RMI4 sensor talking to the bus, and don't forget to unregister later. periodt. 💅

sign-off szn: this little gem lives in ./drivers/input/rmi4, dated October 2026, and it's brought to you by the rmi_registe...sport_device(9) gang — yes the title is truncated, no we don't know why, and honestly? we're obsessed anyway. 🍓🧚💜
