mtd_device_unregister(9)

💅 mtd_device_unregister(9)

okay so this is a page from the Kernel API Manual, and bestie, it's shorter than my attention span but it matters — it's the "bye-bye, MTD device" function. Let's get into it 🎀

---

✨ NAME ✨

mtd_device_unregister — unregister an existing MTD device. that's it, that's the whole vibe. it takes a device that's currently registered and says "you're done here, queen" 👑

---

🌸 SYNOPSIS 🌸

int mtd_device_unregister (struct mtd_info *master );

that's the whole signature, no cap. returns an int, takes one pointer, slays ✨

---

🦋 ARGUMENTS 🦋

• master — the MTD device to unregister. and listen, this is the important part: this will unregister both the master and any partitions if registered. so like… it's not just kicking out the main character, it's taking the whole friend group with it. group unregister. periodt 💀

no cap, if there are partitions registered, they're going too. plan accordingly 🫶

💖 that's the whole page bestie. short, sweet, and honestly kind of a baddie for how much cleanup it does in one call.

and finally, the cute little sign-off: this page comes from ./drivers/mtd, dated October 2026 — and honestly? she ate. see you in the next manpage, mwah 💅✨🍓
