🌸 NAME 🌸

ubi_debugfs_init_dev — the function that sets up debugfs for one (1) UBI device. that's it, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

int ubi_debugfs_init_dev(struct ubi_device *ubi);

like… one function, one argument, zero drama. we love a low-maintenance icon ✨

🍓 ARGUMENTS 🍓

• ubi — the UBI device description object. yes, the struct itself. it's the main character here 👑

---

💜 DESCRIPTION 💜

so what does she do? this function creates all the debugfs files for the UBI device ubi — all of them, every single one, no cap 🫶

then she tells you how it went:

• zero → slay, success, we ate 💖
• a negative error code → nope, it failed, something went wrong 😭

that's literally the whole contract. no hidden lore, no secret side quests 🌈
