💖 cm32181_reg_init(9) — kernel API manual, bestie edition 💖

Okay so picture this: it's a kernel API manual page, section 9, and the star of the show is cm32181_reg_init. That's the whole vibe. Let's get into it 🫶

✨ NAME ✨

cm32181_reg_init — literally just here to initialize the CM32181 registers 💅

🌸 SYNOPSIS 🌸

int cm32181_reg_init (struct cm32181_chip *cm32181 );

That's the whole signature, no cap. Returns an int, takes one pointer. Slay.

🎀 ARGUMENTS 🎀

  • cm32181 — the pointer of struct cm32181. Yep, that's the thing you're handing over. It's giving "here bestie, take the pointer" 🦋

💫 DESCRIPTION 💫

So what does it do? It initializes the CM32181 ambient light sensor register to default values. That's it. That's the whole job. Lowkey iconic, highkey essential — like, somebody's gotta set the defaults, and today that somebody is this function 🌈✨

⭐ RETURN ⭐

  • 0 for success 🎉
  • otherwise for error code 😭 (so like, if you get anything that isn't 0, that's your sign something went sideways)

👑 SEE ALSO 👑

Kernel file ./drivers/iio/light/cm32181.c, plus the whole friend group:

Go read those too, iykyk 📚💜

fr fr, if you only remember one thing: cm32181_reg_init sets the CM32181 ambient light sensor registers to their defaults, and 0 means you ate 🔥

And that's a wrap on our little manual page moment 🧚 This one lives over in the kernel tree at ./drivers/iio/light, dated October 2026 — so go forth, set those defaults, and stan the ambient light sensor 💖🍓
