v4l2_i2c_subdev_init(9)

💅 v4l2_i2c_subdev_init(9) 💅

welcome to the Kernel API Manual, bestie — today’s main character is v4l2_i2c_subdev_init(9), and she is literally here to set things up ✨

🌸 NAME 🌸

okay so v4l2_i2c_subdev_init(9) initializes a &struct v4l2_subdev with data from an i2c_client struct. no cap, that’s the whole name vibe 💅

✨ SYNOPSIS ✨

bestie, here’s the exact signature — do not come for me, I copied it character for character 🫶

void v4l2_i2c_subdev_init (struct v4l2_subdev *sd , struct i2c_client
       *client , const struct v4l2_subdev_ops *ops );

🎀 ARGUMENTS 🎀

• sd — pointer to struct v4l2_subdev. this is the subdev being initialized, she’s the moment 💖
• client — pointer to struct i2c_client. the i2c client struct supplying the data, iconic source energy 🦋
• ops — pointer to struct v4l2_subdev_ops. the ops pointer, aka the operations table vibe 👑
