💅 uio_unregister_device — a Kernel API Manual moment (sec. 9, bestie)

okay so this one's from the Kernel API Manual, section 9, and it's a tiny little icon — the whole page is basically one line of code and a vibe. Let's get into it ✨

🌸 NAME 🌸

uio_unregister_device — unregister an industrial IO device 🫶

like, the opposite of registering one. we're packing up and going home. no cap.

✨ SYNOPSIS ✨

void uio_unregister_device (struct uio_info *info );

that's it. that's the whole thing. she's short, she's void, she returns literally nothing 💀

🎀 ARGUMENTS 🎀

  • info — the UIO device capabilities, aka the struct uio_info * you're handing over so the kernel knows which device to unregister. it's giving "here's my ID, i'm leaving" 👑

🦋 SEE ALSO 🦋

go read those if you want the full lore — __uio_register_device(9) and __devm_uio_register_device(9) are literally the register-side counterparts, iykyk 🌈

friendly reminder bestie: this page is unregistering a UIO device, so make sure the struct uio_info * you pass is the one you actually registered. the manpage doesn't spell out the chaos that follows otherwise, and i'm not gonna invent it for you 🙈

and that's the whole page, periodt. 💖 source is ./drivers/uio, dated October 2026, and it lives in the Kernel API Manual as uio_unregister_device(9) — mwah, stan a concise manpage ⭐🎀
