💖 device_set_driver_override(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶. Today's main character is device_set_driver_override, a tiny lil helper that has ONE job and honestly? it ate.

---

✨ NAME ✨

device_set_driver_override — the helper that sets or clears a driver override. that's it. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

int device_set_driver_override (struct device *dev , const char *s );

like look at her. so simple. so iconic. ⭐

---

🎀 ARGUMENTS 🎀

• dev — the device you're changing. the one getting the glow-up ✨
• s — a NUL-terminated string, aka the new driver name you wanna force a match with. and if you wanna clear it? pass an empty string — "" or "0, where the latter is only for the sysfs interface. yes that's literally what the docs say, and no I will not be elaborating further because that's all we got 😭

lowkey that's the entire page, bestie — we survived, and honestly we slayed 📚💅

byeee 🧚 mwah 💜

so this whole thing lives under ./include/linux, it's the Kernel API Manual edition, dated October 2026, and it will forever answer to the name device_set_driver_override(9). periodt. 👑🌈
