🌸 NAME 🌸

driver_for_each_device — iterator for devices bound to a driver. 💅

okay so hi bestie, welcome to the driver_for_each_device(9) page from the Kernel API Manual 💖 this one is short and iconic: it’s the iterator that goes through a driver’s device list.

✨ SYNOPSIS ✨

int driver_for_each_device (struct device_driver *drv , struct device *start , void *data , device_iter_t fn );

🎀 ARGUMENTS 🎀

• drv — the driver we’re iterating. 👑
• start — the device to begin with.
• data — data to pass to the callback. 🫶
• fn — the function to call for each device. ✨

🦋 DESCRIPTION 🦋

Literally iterate over drv’s list of devices, calling fn for each one. That’s the vibe. No cap. 💖
