void of_device_make_bus_id (struct device *dev );

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this routine will first try using the translated bus address to derive a unique name. slay, easy win.

but if it cannot do that? no stress, it doesn't just give up 💅 it will prepend names from parent nodes until a unique name can be derived. like it keeps climbing up the family tree until the name is, at long last, unique. main character energy from the parent nodes fr fr 👑
