ab8500_fg_sysfs_init(9)

💅 ab8500_fg_sysfs_init — init of sysfs entry

okay so this is from the Kernel API Manual (section 9, kernel functions, iykyk) and it's honestly a little icon: it's the function that gives your fuel gauge its very own sysfs moment. 🎀

---

✨ NAME ✨

ab8500_fg_sysfs_init — init of sysfs entry

like, it sets up the sysfs entry. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int ab8500_fg_sysfs_init (struct ab8500_fg *di );

---

🧚 ARGUMENTS 🧚

• di — pointer to the struct ab8500_chargalg. yes bestie, the manpage really does say ab8500_chargalg here even though the parameter type is struct ab8500_fg *, and we are reporting it exactly as written, no edits, periodt. 💅

---

🔥 DESCRIPTION 🔥

This function adds an entry in sysfs. that's it, that's the main character energy. ✨

Returns an error code in case of failure, else 0 (on success). so 0 = slay, non-zero = something went sideways, check it. 😭

and that's the page bestie 💖 no cap. this cutie came out of ./drivers/power/supply and the docs are dated October 2026 — so go forth, init that sysfs entry, and remember: 0 on success is the only acceptable ending. 🌈👑🍓
