✨ i3c_bus_for_each_i3cdev(9) ✨

okay bestie so this is from the Kernel API Manual and it's literally the cutest lil loop helper — let's get into it 🎀

---

💖 NAME 💖

i3c_bus_for_each_i3cdev — loops over every single I3C device that's chilling on the bus 🦋

---

🌸 SYNOPSIS 🌸

i3c_bus_for_each_i3cdev (bus , dev );

---

🧚 ARGUMENTS 🧚

• bus — the I3C bus, aka the main character of this whole operation 👑
• dev — an I3C device descriptor pointer that gets updated to point at the current slot each time the loop goes around 🔄 (yes bestie it moves, that's the whole point)

---

⭐ DESCRIPTION ⭐

Iterate over all the I3C devs that are present on the bus. that's it, that's the vibe ✨ lowkey iconic how simple it is fr fr 💅

🔥 SEE ALSO 🔥

Kernel file ./include/linux/i3c/master.h and honestly a whole friend group of structs and helpers — here's the full roll call:

struct i3c_i2c_dev_desc(9), struct i2c_dev_boardinfo(9), struct i2c_dev_desc(9), struct i3c_ibi_slot(9), struct i3c_device_ibi_info(9), struct i3c_dev_boardinfo(9), struct i3c_dev_desc(9), struct i3c_device(9), enum i3c_bus_mode(9), enum i3c_open_drain_speed(9), enum i3c_addr_slot_status(9), struct i3c_bus(9), struct i3c_master_controller_ops(9), struct i3c_master_controller(9), i3c_bus_for_each_i2cdev(9), struct i3c_dma(9), i3c_dev_get_master_data(9), i3c_dev_set_master_data(9), i2c_dev_get_master_data(9), i2c_dev_set_master_data(9), i3c_dev_get_master(9), i2c_dev_get_master(9), i3c_master_get_bus(9)

all of them ate, no cap 💀🫶
