devm_i2c_new_dummy_device(9)

✨ NAME ✨

okay so welcome to devm_i2c_new_dummy_device(9), fresh from the Kernel API Manual, bestie 💖 the whole point of this icon is to return a new i2c device bound to a dummy driver — that's the name and the game, periodt.

🌸 SYNOPSIS 🌸

       struct i2c_client * devm_i2c_new_dummy_device (struct device *dev ,
       struct i2c_adapter *adapter , u16 address );

🫶 ARGUMENTS 🫶

• dev — device the managed resource is bound to. This is the device your managed resource is tied to, no cap 🎀
• adapter — the adapter managing the device. It's the adapter in charge, the main character of this situation.
• address — seven bit address to be used. Yep, the seven bit address, exactly as advertised.

😴 CONTEXT 😴

can sleep 😴 — literally, that's the context. This one can sleep, bestie.

💅 DESCRIPTION 💅

Okay so here's the tea: this is the device-managed version of i2c_new_dummy_device. It returns the new i2c client or an ERR_PTR in case of an error. That's the whole flex — new i2c client, or ERR_PTR if things go sideways. 💅
