add_mtd_device(9)

💅 add_mtd_device 💅

okay so welcome to the Kernel API Manual, bestie — this one's a little function with main character energy 🌟

---

✨ NAME ✨

add_mtd_device — register an MTD device 🎀

---

🌸 SYNOPSIS 🌸

int add_mtd_device (struct mtd_info *mtd );

---

🦋 ARGUMENTS 🦋

• mtd — a pointer to the new MTD device info struct, aka the whole vibe of the device you're introducing to everyone 💖

---

💫 DESCRIPTION 💫

Okay so what this does is it adds your device to the list of MTD devices currently present in the system — like sliding into the group chat and being added to the roster 📋✨ — and then it notifies every currently active MTD 'user' that your device has arrived. Not me being the one to announce the new member to literally everyone 🫶

It returns zero on success, or non-zero on failure. periodt 💅
