module_i3c_i2c_driver(9)

💅 module_i3c_i2c_driver — like, the Kernel API Manual, bestie

okay so real talk, this one lives in the Kernel API Manual and it's called module_i3c_i2c_driver, and it's genuinely one of those macros that just gets you. no notes. 🫶

✨ NAME ✨

module_i3c_i2c_driver — the macro that registers a module giving you both an I3C driver and an I2C driver. two for the price of one, we love a bundle 💖

---

🎀 SYNOPSIS 🎀

module_i3c_i2c_driver (__i3cdrv , __i2cdrv );

that's it. that's the whole call. slay. ✨

---

🌸 ARGUMENTS 🌸

• __i3cdrv — the I3C driver you wanna register 👑
• __i2cdrv — the I2C driver you wanna register 🦋

two little drivers, hand in hand, walking into the kernel together. iconic.

---

💫 DESCRIPTION 💫

so basically this macro hands you generic init/exit functions that just... register and unregister an I3C driver and an I2C driver. no cap, that's the whole job. 🔥

the cute part? this macro can be used even if CONFIG_I3C is disabled — and in that case, only the I2C driver will be registered. it adapts. it's flexible. main character energy fr fr 💅

the vibe check: this should be used by any driver that does not require extra init/cleanup steps. if you've got custom setup work to do, this macro is not the one for you, bestie — it's strictly the no-fuss, plug-and-play situation. 🙈
