module_i2c_driver(9)

okay so bestie, this is module_i2c_driver(9) from the Kernel API Manual, and it's the helper macro that registers a modular I2C driver. literally the “make it official” button for your I2C driver era. 💖

---

✨ NAME ✨

module_i2c_driver — Helper macro for registering a modular I2C driver. periodt. 💅

---

🌸 SYNOPSIS 🌸

module_i2c_driver (__i2c_driver );

---

💅 ARGUMENTS 💅

• __i2c_driver — the i2c_driver struct. that's the whole argument, bestie. 🫶

---

🎀 DESCRIPTION 🎀

This macro is for I2C drivers that do not do anything special in module init/exit. it's giving “delete the boilerplate, keep the vibes” because it eliminates a lot of boilerplate. ✨

important: each module may only use this macro once, and calling it replaces module_init and module_exit. no cap, that's the rule. 💀
