bus_unregister(9)

🎀 NAME 🎀

bus_unregister — remove a bus from the system, bestie. This is the bus_unregister(9) page from the Kernel API Manual, and we are gonna get you fluent in it. No cap. 💖

✨ SYNOPSIS ✨

void bus_unregister (const struct bus_type *bus );

🌸 ARGUMENTS 🌸

• bus — the bus. That's the argument. Just the bus. 🫶

💅 DESCRIPTION 💅

okay so here's the tea: bus_unregister unregisters the child subsystems and the bus itself. Finally, we call bus_put to release the refcount. That's the whole sequence, and it's lowkey iconic. 😭✨
