i3c_bus_maintenance_unlock(9)

💅 i3c_bus_maintenance_unlock(9) — like, the kernel API manual bestie ✨

Okay so we're in the Kernel API Manual today and the star of the show is i3c_bus_maintenance_unlock(9). Buckle up, this one's a shortie but she matters. 🎀

---

✨ NAME ✨

i3c_bus_maintenance_unlock — release the bus lock after a maintenance operation 🫶

Lowkey the whole personality: you held the lock, you did your lil maintenance thing, now you let go. Iconic behaviour, no notes. 💅

---

🌸 SYNOPSIS 🌸

void i3c_bus_maintenance_unlock (struct i3c_bus *bus );

Yes bestie, that's the whole signature. Returns void, takes one pointer, zero drama. 🦋

---

🧚 ARGUMENTS 🧚

• bus — the I3C bus you're releasing the lock on. That's her. That's the one. 💖

---

🔥 DESCRIPTION 🔥

Should be called when the bus maintenance operation is done, periodt. ✨

And if you're sitting there like "wait, what even is a maintenance operation??" — same, but the manpage says: see i3c_bus_maintenance_lock for more details on what these maintenance operations are. So go read that one, iykyk. 📖

Not me reminding you that this is the unlock half of the duo — if you never called the lock, you're gonna have a bad time. 🙈
