💅 ab8500_fg_get — Kernel API Manual, bestie edition ✨

Okay so real talk, this little function is from the Kernel API Manual and it's genuinely one of the easiest glow-ups in the whole AB8500 saga, so let's get into it 🫶

---

🌸 NAME 🌸

ab8500_fg_get — returns a reference to the primary AB8500 fuel gauge</> (i.e. the first fuel gauge in the instance list). That's it. That's the whole job. She's the main character of the fuel-gauge friend group 💅

---

✨ SYNOPSIS ✨

struct ab8500_fg * ab8500_fg_get (void );

Returns a struct ab8500_fg *, takes absolutely nothing, periodt.

---

🎀 ARGUMENTS 🎀

• void — no arguments. Zero. None. She needs no input, she simply is 🦋 (ngl kind of iconic of her)

Lowkey a flex that one tiny getter has this many cousins, but go off AB8500 family 👑
