💅 pch_i2c_cb(9) — bestie's guide to the interrupt handler callback

okay so welcome to the Kernel API Manual, section 9, and today's main character is pch_i2c_cb(9) — literally the interrupt handler Call back function. yes that capital C is canon, we don't question the ancients 🫶

✨ NAME ✨

pch_i2c_cb — Interrupt handler Call back function 🎀

that's it. that's the whole vibe. it's the callback that shows up when the interrupt handler needs someone to handle business. no cap.

---

🌸 SYNOPSIS 🌸

void pch_i2c_cb (struct i2c_algo_pch_data *adap );

returns void, takes exactly one pointer, and it's giving "small function, big responsibilities" energy. iconic honestly 👑

🦋 ARGUMENTS 🦋

• adap — Pointer to struct i2c_algo_pch_data. that's the one thing it wants from you. hand it over and let her cook 🍓
