recall_eeprom(9)

💖 recall_eeprom — bestie, it's giving "restore" ✨

okay so first things first, we're in recall_eeprom(9) — that's section 9 of the Kernel API Manual, the deepest lore, and it's literally about putting your EEPROM data back where it belongs. no cap. 🎀

---

🦋 NAME

recall_eeprom — restore EEPROM data to device RAM

like… it goes and gets the data out of the EEPROM and pops it back into the device's RAM. lowkey iconic behaviour honestly. ✨

---

🌸 SYNOPSIS

int recall_eeprom (struct w1_slave *sl );

that's it, that's the whole vibe. one function, one pointer, one int coming back at you. 🫶

---

🍓 ARGUMENTS

• sl — slave involved. that's the struct w1_slave * bestie, the actual slave we're working on. it's not decorative, it's the whole main character of this call. 💅

---

🔥 RETURN

• 0 if success — slay, it worked, we ate and left zero crumbs 👑
• -kernel error code otherwise — so like, on failure you get a negative kernel error code. not me getting a negative number as a personality trait 😭

fr fr, if it's not 0, something went sideways and the error code is telling you exactly how. read it, don't ignore it. 💀

quick vibe check reminder: all the literal stuff above — function names, paths, struct names, numbers — stays exactly as written. copy-paste energy only. don't go reinventing flags, bestie. 🙈
