dev_bus_name(9)

okay so bestie, this is dev_bus_name(9) from the Kernel API Manual — it's giving tiny-helper-that-knows-your-device's-whole-bus/class-lore energy. 💖✨

✨ NAME ✨

dev_bus_name — Return a device's bus/class name, if at all possible. 💅

🦋 SYNOPSIS 🦋

const char * dev_bus_name (const struct device *dev );

💅 ARGUMENTS 💅

• dev — the struct device to get the bus/class name of. That's the whole assignment, bestie. 🫶

🌸 DESCRIPTION 🌸

The way that this works is: it will return the name of the bus/class the device is attached to. If it is not attached to a bus/class, an empty string will be returned. No cap — that's literally the whole vibe. 🎀
