nanddev_unregister(9)

🦋 nanddev_unregister — kernel API manual, bestie edition 🦋

okay so this is a page from the Kernel API Manual, and today's main character is nanddev_unregister. yes it's a 9 (kernel section, iykyk). let's get into it 💅

---

✨ NAME ✨

nanddev_unregister — unregister a NAND device

like, the opposite of registering one. the breakup arc 🥀

---

✨ SYNOPSIS ✨

int nanddev_unregister (struct nand_device *nand );

---

✨ ARGUMENTS ✨

• nand — the NAND device. that's it. that's the whole argument. she's low maintenance 👑

---

✨ DESCRIPTION ✨

Unregister a NAND device. super straightforward, no cap.

but here's the tea ☕ — this function is literally just a wrapper around mtd_device_unregister, which unregisters the MTD device embedded in nand. so like, nanddev_unregister is the vibe, mtd_device_unregister is the one actually doing the work. she's giving delegation, she's giving manager energy, and honestly? iconic.

---

✨ RETURN ✨

0 if it slayed (success), and a negative error code otherwise. so always check your return values bestie, 0 is the good one 🫶
