ab8500_fg_sysfs_exit(9)

💅 ab8500_fg_sysfs_exit(9) — the kernel API manual page, bestie edition ✨

okay so real talk, you're deep in the kernel API manual (Kernel API Manual, section 9) and you've stumbled onto the cleanup girlie of the ab8500 fuel gauge family. she's the last one out, she turns off the lights. let's get into it 🫶

---

🌸 NAME 🌸

ab8500_fg_sysfs_exit — de-init of sysfs entry. that's it, that's the whole job: she de-inits the sysfs entry. icon behavior, no notes 💅

---

✨ SYNOPSIS ✨

void ab8500_fg_sysfs_exit (struct ab8500_fg *di );

yes, she returns void. she gives nothing and she takes nothing (except the one pointer, see below). main character energy honestly 👑

---

🎀 ARGUMENTS 🎀

• di — pointer to the struct ab8500_chargalg. that's the one thing you hand her, and she handles the rest ✨

---

💖 DESCRIPTION 💖

so what does she actually do? this function removes the entry in sysfs. that's the whole vibe check. entry gone. sysfs cleansed. slay 💅

no cap, that's literally the documented behavior — she removes the entry in sysfs, periodt. don't go reading extra ✨mystery✨ into it, iykyk.
