✨ NAME ✨

v4l2_i2c_subdev_unregister — the one where you unregister a v4l2_subdev 🎀 like, it's over, it served its purpose, we're closing the tab on it.

🌸 SYNOPSIS 🌸

void v4l2_i2c_subdev_unregister (struct v4l2_subdev *sd );

the way that return type is just void... it gives "no thoughts, just vibes, and also no error code" 😌

---

🦋 ARGUMENTS 🦋

• sd — pointer to struct v4l2_subdev 💫 that's the subdev you're sending off. yes, a pointer. you hand it the address of the struct, not the struct itself. slay, but carefully 🫶
