nanddev_register(9)

✨ nanddev_register(9) ✨

okay so this is a page from the Kernel API Manual — yes, the kernel has its own manual, we love a documented kernel 💅 — and today's main character is nanddev_register. buckle up bestie, it's short but it's important. 🎀

---

🌸 NAME 🌸

nanddev_register — literally just: register a NAND device. that's the whole vibe. no cap. ✨

---

🦋 SYNOPSIS 🦋

int nanddev_register (struct nand_device *nand );

that's it. one function, one argument, returns an int. iconic minimalism 🫶

---

🍓 ARGUMENTS 🍓

• nand — the NAND device. that's your struct nand_device * right there. hand it over and it gets registered. 💖

---

🌈 DESCRIPTION 🌈

so what does it actually do? it registers a NAND device. that's the headline, periodt. 👑

but here's the tea: this function is just a wrapper around mtd_device_register — like, it's not doing some secret extra magic, it's registering the MTD device that's embedded in nand. so if you were expecting extra steps, nope 🙈 it's giving "small function, big responsibility." very main character energy honestly. ⭐

---

🔥 RETURN 🔥

• 0 — success!! slay 💅 you did it.
• a negative error code — otherwise 😭 something went sideways.

ok bestie quick recap: one function, one arg, returns 0 or a negative error, and it's a thin wrapper over mtd_device_register for the MTD device embedded in nand. go register that device. you got this 💪💖
