💅 cs4270_i2c_remove(9) 💅

hey bestie, welcome to the Kernel API Manual entry for cs4270_i2c_remove — this is the lil cleanup function that deinitializes the I2C interface of the CS4270, and yes, it’s giving “last one out, turn off the lights” energy 💡✨

---

🌸 NAME 🌸

cs4270_i2c_remove — deinitialize the I2C interface of the CS4270

okay so literally: this function’s whole job is deinitializing the I2C interface of the CS4270. no cap. 🎀

---

✨ SYNOPSIS ✨

void cs4270_i2c_remove (struct i2c_client *i2c_client );

it returns void, bestie — so don’t go looking for a return value, there isn’t one 🫶

---

🎀 ARGUMENTS 🎀

• i2c_client — the I2C client object. that’s the thing you hand over, and its type in the synopsis is struct i2c_client * 🦋

---

🦋 DESCRIPTION 🦋

when the i2c device is removed, this function puts the chip into low power mode. that’s the whole vibe: device goes bye-bye, chip gets tucked into low power mode, and the CS4270 is not left out here burning unnecessary energy 😭💤

lowkey iconic behavior, honestly. the way that cleanup functions just do their one thing and leave? obsessed. 🔥
