✨ cmm_sysfs_register(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's short and sweet, literally a little baby function page, but it's lowkey important so let's get into it 🫶

---

🌸 NAME 🌸

cmm_sysfs_register — registers with sysfs 💖 like, that's the whole gig, that's the vibe, that's what she does ✨

---

🦋 SYNOPSIS 🦋

int cmm_sysfs_register (struct device *dev );

that's it, that's the signature, no cap 🔥

---

🎀 ARGUMENTS 🎀

• dev — okay so bestie, the manpage literally says -- undescribed -- 😭 like the docs said "we don't know her, never met her" 💀 so fr fr, nobody wrote down what dev does here. It's a struct device * and that's all we're getting. Iconic of them tbh. Not me reading the source to find out—anyway 🙈

---

👑 DESCRIPTION 👑

so like, here's the tea ☕:

• Return value: 0 on success / other on failure 🍓

that's it. that's the description. she's a woman of few words and honestly? respect 💜

ngl if you only remember one thing, remember the return value bestie — 0 means slay, anything else means something went sideways 😭 keep an eye on it 🔥
